Rotation

Sample Problem

Sample Problem While you are operating a Rotor (the rotating cylindrical ride discussed , you spot a passenger in acute distress and decrease. (a) What is the constant angular acceleration during this decrease in angular speed? SOLUTION: Assume that the rotation is in the counterclockwise direction, and let the acceleration begin at time I = 0, at angular position 60, …

Rotation with Constant Angular Acceleration

Rotation with Constant Angular Acceleration In pure translation, motion with a constant linear acceleration (for example, that of a falling body) is an important special case.We displayed a series of equations that hold for such motion. In pure rotation, the case of constant angular acceleration is also important. and a parallel set of equations holds for this case also. …

Angular Position

Angular Position Shows a reference line, fixed in the body, perpendicular to the rotation axis, and rotating with the body. The angular position of this line is the angle of the line relative to a fixed direction, which we take as the zero angular position.The angular position 9 is measured relative to the positive direction of the , …
