What is the principle of the twisting car that children play?

It's two crossed curves. A point supports the ground, and a point swings forward. When turning in a different direction,. Change to another fulcrum and swing forward.

The twist car is played as follows:

1. Play 1: Sit in the car and control the steering wheel with your hands, and your feet are slippery.

3. Play 3: Turn the body side aside, and turn the wheels vigorously with your hands, and the wheels will shine because of the rapid rotation.

4. Play 4: Because the height is very suitable, stand and push the twisting car forward or backward, a bit like a walker.

5. Play 5: Use the tow rope to lead the twisting car together.

Place the drift bike on the ground in a straight position, press the power switch, the switch indicator and battery indicator light will light up, and the buzzer will sound at the same time, and then you can start riding.

The twisting car uses the principle of centrifugal force and the principle of inertia in human movement, and can drive back and forth at will only by turning the steering wheel left and right.

Twist car, also known as children's exercise bike, swing car, the main body is made of engineering polypropylene, made of injection molding, stable structure, simple operation, no need for batteries and transmission devices, as long as the steering wheel is turned left and right, you can drive back and forth at will. It is an environmentally friendly green toy, which first appeared in Taiwan, China. At the same time, it is also called a fitness and recreational car, no need to charge, no fuel, no winding, no pedals, just use your hand to shake the steering wheel left and right to drive, this car has magic power, its driving principle is to use the centrifugal law wide barrier and curve force law, no need for electric energy, fuel and clockwork drive, can move freely.

It's easy to operate and doesn't require a battery.

Research on the forward (backward) principle of a torsion car.

1. Research motivation.

One day, I saw the teacher's two-year-old son playing with the twisting car, which has a simple structure and no electricity, no motor, can move forward, backward, and turn in place, which is a very ordinary toy. Later it was found that two-year-old toddlers used small ones.

The power, which can carry a teacher of 65, keeps twisting and turning to do zigzag forward, which is amazing.

Name, Quantity, Specification, Use.

Twist car 1 net weight, weight resistance 120 Research topic.

Carbon paper: 12 sheets, A4 size. Measure the trajectory of movement.

Level 1 2 directions Check whether the floor is level.

Large right-angled plates 2 with scales to measure dimensions.

Lifting weights uses discs of 4 total weights instead of the person's weight.

Digital scale 1 weighing 136, minimum scale Measure the positive force of the wheel.

1 weighing weight 3, minimum scale measuring horizontal tension spring scale.

1 piece weighs 10 and the minimum scale measures the horizontal tension.

3, Experimental setup:

Description]: Bottom view of the torsion car (not to scale), where.

1.A, B is the front wheel, C, D is the rear wheel, and the center K is the rotating shaft. Use i to indicate the position of the wheel, square.

Pointing to the hinge.

2.r is the distance from the hinge to the handle, and the front wheel takes r as the radius, which can be used for circular rotation.

3.Look at the handle for W, turn the handle, then the twisting car can move forward (,07,08).

4.The eye sees that the handle is m, and if you turn the handle, the twisting car can be reversed (,10,11).

5.The front wheel and the shaft of the twisting car are about a regular triangle after measurement, the position of the vertex is the rotating shaft, and the two bottom corners are the position of the front wheel.

6.Regardless of whether the twisting car is forward or backward, the force applied in the tangential direction f and the direction of the wheel, the angle is always.

7.When people operate the twisting car, they will change the position of the center of gravity due to the rotation of the handle.

There are 4 pieces of hanging weight discs for weightlifting, which are fixed on the twisting car seat and are separated from the rear wheel center perpendicular line.

Friction with the ground to generate kinetic energy.
