Is it easy for the bus to roll over Why, explain it with physics knowledge

When the center of gravity of an object falls in the plane formed by its support points, the object will not tip over.

The support point of the bus is its front and rear wheels, connect the front and rear wheels, will get a rectangle, as long as the center of gravity of the bus falls in this rectangle, the bus will not roll over, but when the bus turns too sharply, under the action of centrifugal force, the center of gravity will be shifted, when the center of gravity is offset out of the plane composed of the front and rear wheels, the bus will roll over. Of course, as for the side of tolerance, it is necessary to consider factors such as vehicle type, road conditions, and speed.

No, because the general chassis of the vehicle will be very heavy, so the center of gravity is very low, and because the bus is large, during production, the ground will be heavier, and the center of gravity is also very low, and it will generally not turn over. Unless the turn is very sharp or the production is unqualified.

From a physical point of view, the larger the aspect ratio, the more likely the center of gravity is to shift.

The center of gravity is too high, unstable and prone to rollover.

The centripetal force f=mv r, m is large, the centripetal force f is greater, in addition, f=mw r, the angle of rotation per unit time is large, the angular velocity is larger, f is larger, and f is not enough, it rolls over.

The mass of the bus is large and the center of gravity is high, and if you draw a force analysis diagram, it is easy to roll over.

No, because the center of gravity is very low, it generally does not turn over.

Principle of centripetal force: when the vehicle is turning, there will be a centripetal force to the inward side, if the two sides of the highway are at the same height at this time, then the car will be affected by the centripetal force to the inward, easy to roll over; The inner side is lower than the outer side, which will make the vehicle have an inclination to the inward, and at this time, the component of the ground force on the vehicle in the horizontal direction will become a centripetal force, so that the vehicle is not easy to roll over.

When turning on a highway in the middle of a highway, the outside of the highway should be high (on the outside of the circle) and the inside should be low (on the center of the circle), so what is the linearity called? After the end of the curve, the height of the road surface is basically the same, and the calculation method of the gradual change process when the master points out the turning section?

Increases the centripetal force to prevent the vehicle from exiting the curve.

When making a sharp turn, the car needs to have horizontal friction with the ground to act as a centripetal force, and the force analysis shows that the friction is parallel to the ground, and the center of gravity of the car is higher than the ground, so that the car has a tendency to overturn in the direction of the turn, the greater the speed, the higher the center of gravity, the easier it is to roll over

1. When the car turns sharply, the car will produce inward friction between the wheels on the ground due to its own weight, but the centrifugal force at the center of gravity of the body will be thrown outward, and the two form the torque of turning outward, if the speed is not too fast, the friction affected by gravity will keep the car safe, otherwise it will overturn.

2. Gravity, support, and table friction, of which gravity and support are a pair of balancing forces.

The friction force is not enough to provide the centripetal force, and the car will do centrifugal motion.

1. Riding too fast is not good for braking. umg=ma;

a=ug=fixed value;

t=v/a;

T is proportional to V, so the faster you ride, the harder it is to brake.

2.Not conducive to cornering. v (safe speed, excluding road inclination) 2 r=ma=umgIf v is actually greater than the above v, the car will roll over.

When traveling, you must be calm, follow the arrangement, don't run around, especially in the car, sit well, don't swarm in one place and cause an imbalance in the car!

As some tourists, I think that when traveling, we should first pay attention to this safety, and since I get on this bus, I must fasten my seat belt in the future, so that I think it is possible to make myself better, and the so-called seat belt is the life belt.

When traveling, you should pay more attention to the surrounding environment, for example, when taking the bus, you should see if there is a safety hammer, and when you take the boat, you should pay attention to whether there are life jackets and whether the number of life jackets is enough. It's also a good idea to look at the local environment and look up more information. Prevent it before it happens.

The rollover incident of the Russian tourist bus warns tourists to pay attention to personal safety when traveling, wear seat belts no matter what kind of car they do, and learn more ways to save themselves, and do not panic.

Be sure to pay attention to your own safety and remember the guide's instructions not to go to dangerous places. It is also necessary to choose a large tour company that is more formal.

When traveling, you should choose a regular and large travel company, because these companies will buy you the corresponding insurance to protect your safety. Although I don't know why the bus rolls over, it tells us that we still need to fasten our seat belts when it is critical to ensure our safety.

First of all, pay attention to the escape tools on the vehicle, and how to use it. The second is to obey the command of the staff, learn more first aid methods, and calmly respond to danger.

This kind of rollover is not something that the person participating in the tour can control...It's clearly a problem with the driver and the vehicle...What else can travelers pay attention to....

When traveling, you should not run around and follow the instructions of the tour guide. Look at the car as well when you get on it. Vehicle maintenance is not qualified in all aspects.

In many cases, the bus rolls over because the driver has violated the rules, but there are also rollovers caused by emergency avoidance of pedestrians or vehicles and sharp turns. It is also possible that the tires are too old, resulting in a decrease in friction and a tendency to roll overBuses are very different from ordinary cars, so they are more likely to roll over while driving.

Vehicle rollover, often because the vehicle's center of gravity is too high or left and right unbalanced, the wheel base is relatively too small, the steering speed is too fast, the braking force of the left and right vehicles is unbalanced and the ground friction is unbalanced, etc., resulting in the horizontal component of the vehicle rollover force is greater than the lateral component of the vehicle's own gravity. Therefore, in the process of driving, when encountering these situations, the driver must beSlow down, drive at medium or low speed, take control of the steering wheel, don't over-adjust the wind direction, pay attention, observe the road conditions well, and try to choose a better road surface to pass.

When the vehicle is half-rolled over or rolled over, then the owner should not start the vehicle again at will to get the vehicle over, which is very dangerousCheck the car for oil leaks, and if there is an oil leak, you should flee in time, thinking that there is a possibility of a fireIf not, the vehicle battery can be removed. It is best to have the relevant personnel use tools to turn the vehicle over and finally send it to the repair shop for a complete overhaul.

In the event of a rollover accident, the driver and passengers may be in a handstand position, and the human body will be suspended in the cabin due to the effect of the seat belt, so as to protect the head and neck from injury. Please do not rush to unfasten your seat belt after a rollover, because unfastening your seat belt without preparation is like turning you upside down and falling your head down on the ground, which can easily hurt someone.

I think it's possible, after all, it's also drowsy driving, and it's definitely dangerous.

I think there is still a reason for this, because he will definitely have some problems while driving. So there will be a certain danger.

It doesn't have to be a violation, it could be an imbalance on the road, or an obstacle blocking the view.

It cannot be generalized, the rollover is not necessarily because the driver has illegal driving, it may be because of external interference factors, such as pedestrians, the condition of the road, etc., so do not make a judgment easily, mainly depending on the investigation results of the relevant departments.

It is also possible that the bus rolls over and the driver is driving illegally, so be sure to follow the traffic rules.

It may be because the driver is not operating properly, and the center of gravity of the bus is different from that of a normal car, so it is more likely to roll over while driving.

Not necessarily, it may be that the road is bumpy, it is difficult to drive, or it may be caused by the driver slamming the steering wheel.

The most important thing about being away from home is to ensure your personal life and financial security. However, there are always traffic accidents that happen for various reasons. The Guangdong bus accident sounded the alarm for us.

When we are away from home, whether we are taking any public transportation, we must pay close attention to all kinds of traffic hazards while the vehicle is moving. In the event of a rollover or a fire, how should we deal with it correctly? How to escape safely in the first place?

These are all questions that require serious consideration.

I remember that there was an incident of bus ** somewhere before, and many people bought safety hammers on the Internet. And take it with you. Because when the vehicle is suddenly involved in a traffic accident, many survivors are desperately trying to smash the glass, but without a safety hammer, they are powerless.

Now with the upgrading of vehicle manufacturing technology. Especially some fully enclosed buses, the quality of his windows, the glass is very strong and hard.

In the process of passenger panic, even if you have a safety hammer, it is not easy to break the glass easily. So we have a special process for the manufacture of automotive glass. Whether it's tempered or laminated glass.

We all need to master the right way to tap. It is to knock on the edge of the glass all around. Don't smash the middle with great effort.

Whether it is a collision or rollover. Keep a calm and sober mind. Find a way to escape quickly as soon as possible, and don't worry about any luggage you have with you.

Although for the vast majority of people, they have not experienced a road accident. There may be people who don't have many opportunities to travel by long-distance bus on a regular basis. However, we must not be careless and ignore the sudden occurrence of disasters. Have a strong sense of safety and self-protection.

You can break the glass with the special hammer provided on the car to escape.

Pay attention to fasten your seat belt when getting into the car, pay attention to calmly observe the surrounding environment when encountering a rollover, and then calmly break through the window to escape!

When encountering such danger, you should immediately call 119 to call the police, and then use a safety hammer to smash the glass to escape

Use the small hammer on the car to smash the window and escape.

When it comes to such dangers, I think the first thing is to take your seat belt and get out of the car as soon as it stabilizes.

No one can do anything about this kind of thing, so let's just get in the car and fasten your seatbelt.

First check to see if you are injured, and then make sure you are free to call 120.

At this time, the first thing you should do is to ensure your safety, fasten your seat belt, and hold on to the seat of this car.

First of all, don't panic, check the wound and call an ambulance**.

The serious bus accident in Guangdong made us even more shocked. When we take the bus, we must pay close attention to how to effectively protect our own safety.

At the same time, we must have a comprehensive understanding of the buses we are taking. We need to have basic knowledge, which places are relatively safe to take the bus? Except for fastening your seatbelt, sit tight and don't sleep.

Have an idea of the structure of the bus. We need to make a comparative analysis of various types of vehicle accidents.

In the event of a vehicle collision, where are the seats most likely to be hazardous? After investigation and summary, the traffic management department found that whenever a traffic accident occurred,Usually the left side of the front is where the risk of danger is highest. Then once the rear and front right and **left.

In general, the seat on the left side of the bus has the highest risk chance.

The right side has a relatively low chance of danger. If you sit in the front seat, you will be thrown out of the car by the force of the impact in the event of a traffic accident. The last row is located directly in front of the aisle.

This seat is also relatively low in terms of safety factor, especially when it encounters brakes, it is easy to lean forward. There is no shielding.

Although this seat may feel relaxed and comfortable, please do not sit in this seat. When the vehicle has a sudden traffic accident, you must pay attention and do not panic. Try everything you can to escape from the accident vehicle as soon as possible.

Because of the instantaneous violent impact, it is easy to cause the vehicle to occur, and more serious accidents occur.

The middle position should be the safest, sitting close to the driver's side.

There is no safest area of the bus, in fact, I think it is best to wear a seat belt.

In the middle of the bus, I think it's relatively safe.

The rear of the bus is the most unsafe. The middle is relatively safe.

Passenger car lane, this is fundamental, and don't overload it!

Personally, I feel that it is safer to rely on the driver's side in the middle.

It should be the safest side to be near the driver.

It is safest to take the right side of the front of the bus.

It should be safest to be near the middle.
