Rolling resistance (RR): This depends mainly upon the nature of the ground, the tires used, the weight of the vehicle, and to a lesser extent, the speed (the last variation is usually ignored). Air resistance ( AR ): Air resistance (wind resistance) depends upon the size and shape of the vehicle — its degree of streamlining and increases approximately as the square of the speed through the air.

 · Deadly vertical Gforces go for the head; since they're aligned with the spine, these accelerations can drive blood down toward the feet, and away from the bloodneedy brain. With the development of stronger headtotoe G's, our bodies need to work harder and harder to try and pump blood back up to the brain, and after a while, the heart simply can't summon enough pressure to do so.

 · Before looking at rolling objects, let's look at a nonrolling object. Suppose that I have some frictionless block on an inclined plane. The block can .

 · The vertical (up and down) motion of the ball knows absolutely nothing about the horizontal (sideways) motion. When you throw the ball up while riding the skateboard, the ball keeps going sideways. Because the ball retains its original horizontal motion after it leaves your hands, it ends up in your hands again as if neither you nor the ball had ever moved sideways in the first place.

Horizontal projectile motion is one of the most basic examples of classical physics. Gravity is a force that causes acceleration towards the center of the Earth at m/s causes objects that are falling to increase in speed until they reach their terminal, or maximum, velocity (or until they are stopped by another force, like hitting the ground).

The Falk Lifelign G82 Couplings are rigid couplings used when there is no need to accommodate misalignment and where thrust loads are generated, such as vertical mixer appliions. The coupling carries the torque load, weight of the shaft and impeller, thrust forces, and resulting bending movements.

The study design was a randomized crossover design in which subject performed a series of planking exercises or rolling exercises and then performed a series of athletic performance tests (vertical jump height and power, isometric force, and agility). Fatigue, soreness, and exertion were also measured.

 · Pressure vessels typically consist of a cylindrical shell and elliptical or hemispherical heads at the ends (Peters and Timmerhaus, 2003). Generally, chemical engineers will not be directly involved in detailed mechanical design of pressure vessels. This will be handled by mechanical engineers with experience in the field.

We can use matrices to translate our figure, if we want to translate the figure x+3 and y+2 we simply add 3 to each xcoordinate and 2 to each ycoordinate. [ x 1 + 3 x 2 + 3 x 3 + 3 x 4 + 3 y 1 + 2 y 2 + 2 y 2 + 2 y 2 + 2] If we want to dilate a figure we simply multiply each x and ycoordinate with the scale factor we want to dilate with.
