What is the 45 degree tilt and how many centimeters is the 45 degree tilt

Jackson's classic 45-degree tilt is all about hooked shoes.

Michael Jackson, the king of dancing spirits, has a signature move of standing and leaning forward and ** backward, the secret turns out to be his invention of "anti-gravity dancing shoes", after wearing it, the whole person can tilt straight forward 45 degrees without falling down, which is breathtaking.

In order to enhance the visual effect of himself and the dancers when dancing, Jackson often designed some gravitational forward tilting movements. At first, Michael Jackson used a seat belt around his waist to complete this kind of action, so in his music videos, you can often see the classic forward leaning forward 45 degrees + rotation action, and later this method is not realistic in concerts. Because the rope tied around his waist was impossible to install and remove during a live performance, and it would also restrict body movement, he was determined to invent the "anti-gravity shoe".

Jackson and two costume designers set aside a hook on the heel of a special shoe. When he needs to lean forward, a row of hooks rises on the stage. At this point, the stage creates other visual effects to attract the audience's attention, and Jackson and the dancers take the opportunity to slide the heel of their shoes onto the hook and buckle them before leaning forward.

Of course, even this is inseparable from the hard workouts of Jackson and other dancers, as well as the careful rehearsal and running-in, as well as the strong back muscles and body balance control.

Michael Jackson and two partners patented this invention in 1993. Aaron Kwok also performed at the concert, and he made a special trip to the United States to ask Jackson for advice.

It can't be physically possible.

MJ applied for this patent about 16 years ago.

The problem is in its shoes.

He has a groove in the heel of his shoe.

Somewhere on the ground there will be a place for him to be fixed.

His dance group is the same principle.

But if the waist and abdomen strength.

and the back strength is not strong enough.

It is also impossible to accomplish such an action.

Please don't try it lightly.

Interested in taking a look.

Concert of Dangerous Journey.

There's a backup dancer because of that.

The shoes didn't come out too much.

It's a second slower than everyone else.

I hope to mention more technology in the future.

At the time, this stunt made many fans crazy. In fact, there was a barb on the stage that hooked a groove at the base of the sole of Jackson's leather shoes, and in doing so, it leaned forward.

Michael Jackson wore special shoes that could hold his feet firmly on the ground, and he only needed to exert force at the waist to lean forward 45 degrees.

The special shoes have a mechanical connection between the heel and the stage, which can firmly hold the body support points. Even so, it is inseparable from Mike and the actors' hard workout, as well as careful rehearsal and running-in. It is inseparable from strong back muscles and body balance control!!

45 degrees refers to the degree of an angle, while the centimeter is a unit of length, and the two cannot be equivalent.

45 degrees is not equal to how many centimeters, 1 radian = degrees. According to the definition of radians, the central angle of the arc with the length of the circumference of the circle (2 r) is 2 radians, and the central angle of the arc with half a circumference is radians. Therefore, the conversion relationship between angle and radian is very clear.

Because 360 degrees = 2, therefore, 1 degree = 180 radians, 1 radian = 180 = degrees.

45 degree angle calculation formula

The formula for calculating the 45 degree angle is tan45 degrees = 1, sin45 degrees = 2 2, cos45 degrees = 2 2. Trigonometric function is one of the basic elementary functions, which is a function in which the angle (the most commonly used radian system in mathematics) is the independent variable, and the angle corresponds to the coordinates of the intersection point of the terminal edge of any angle with the unit circle or its ratio as the dependent variable.

It can also be defined equivalently in terms of the length of the various line segments related to the unit circle. Trigonometric functions play an important role in the study of the properties of geometric shapes such as triangles and circles, and are also a fundamental mathematical tool for the study of periodic phenomena. In mathematical analysis, trigonometric functions are also defined as infinite series or solutions to specific differential equations, allowing their values to be extended to arbitrary real values, even complex values.

Slope bridge is a mathematical and geometric term that represents the degree to which a straight line (or tangent of a curve) is tilted with respect to the (horizontal) coordinate axis. It is usually used as the tangent of the angle between the straight line (or the tangent of the curve) and the (horizontal) coordinate axis, or the ratio of the difference between the ordinates of two points and the difference between the abscissa to show the mountain suspicion.

Slope, also known as "angular coefficient", is the tangent of a straight line to the positive angle of the abscissa axis, reflecting the inclination of the straight line to the horizontal plane. The tangent of the angle between a straight line and the abscissa axis of a plane Cartesian coordinate system, that is, the slope of the straight line relative to the coordinate system. If the line is perpendicular to the x-axis, the tangent of the right angle is tan90°, so there is no slope of the line (the slope of the line can also be said to be infinite).

When the slope of the line l exists, for the primary function y=kx+b (oblique truncation), k is the slope of the image of the function.

First of all, from the practical point of view, the slope is what we call the slope, is the average rate of change of height, and the slope is used to depict the inclination of the road, that is, the ratio of the tangential height of the slope to the horizontal length, which is equivalent to moving a thousand meters in the horizontal direction, rising or falling in the tangential direction, and this ratio actually indicates the size of the slope.

Secondly, from the tangent of the inclination angle; In addition, from the perspective of vectors, it is the angle between the vector in the upward direction of the straight line and the unit vector in the direction of the x-axis; Finally, from the perspective of derivatives, we can re-understand the concept of slope, which is actually the instantaneous rate of change of the ordinate of a line with the abscissa.

The reason why Michael Jackson was able to do the dance moves at an inclination of 45 degrees must have everyone wondered how he practiced it.

What can be told to you is that although it is a world-class Uranus superstar, it is completely impossible for a natural person to tilt 45 degrees without relying on external support and not fall, which is completely impossible to achieve in violation of gravity. A little humor to explain to everyone, that is, Michael Jackson also used to cheat sometimes.

It's common sense that it's impossible for anyone to tilt 45 degrees without falling. The reason why Michael Jackson can not fall is in the bottom of the shoe. Because Michael Jackson's shoes have a locking device at the bottom, wearing shoes with this character, let the foot be fixed, and then the center of gravity of the whole body is tilted forward, and the force point is all supported by the waist force.

For this original 45-degree inclined dance step, Michael Jackson even spent money to patent himself.

It is assumed that there is no friction between the rain and the tiles.

Then, the acceleration of the rain when it slides down a = GSINA (a represents the inclination angle of the roof) and the height of the roof is h, and in general, h is unchanged.

Then, the length from the roof to the bottom is l=h cosa, and the rain is evenly sliding (initial velocity is 0).

So, according to the kinematic formula there are:

l=1/2*a*t^2

Solution, t = under the root number (2L g*sina*cosa)] Obviously, when sina*cosa is maximum, t is minimum.

And sina*cosa=1 2*sin2a

When 2a = 90 degrees, sina*cosa is the maximum.

Therefore, when a=45 degrees, the glide time t is the smallest, and the glide time is the fastest.

The seventh single in Michael Jackson's "BAD", the king of pop, was released in November 1988. In the UK, it took the No. 8 spot and became the 5th Top 10 single for "BAD" in the UK. Its market is likewise eaten up by the best-selling **.

But it still stayed in the top 40 for nine weeks, making it the longest-staying single in the UK top 40 on "BAD"** (surpassing "I Just Can.").'t stop loving you" and "the way you make me feel"). One of its great achievements is that it was in the top 20 for 8 weeks.

This record was only achieved by six other singles by MJ ("One Day in Your Life", "Billie Jean", "Thriller" - 9 weeks, "Heal the World", "You Are Not Alone" - 9 weeks and "Earth Song" - 11 weeks) "Bad" had sold 2 million copies in the UK by this time, not only swallowing up a large number of singles market, but also the singles themselves lacked novelty. But it was still widely broadcast, and the exquisite ** video with it has also become a generation of classics. All of this is about fighting for the Christmas market for "BAD"**.

In the U.S., it's another top 10 (No. 7) song. It became the 6th Top 10 Golden Song and the 7th Top 20 Golden Song in "BAD". This is already a record.

It also spent a total of 15 weeks on the pop charts and was runner-up on the R&B charts. Despite this, it became the last single released by "BAD" in the United States.

It has performed very well around the world, finishing in the top 10 in Germany, France and Italy, but suffering defeat in Australia. It also occupies the first place in the Danish and Belgian charts.
