Question

A motor is used to turn the pulley A which is connected to the wheel B by a transmission belt. The system starts from rest. The motor begins to rotate the pulley A with a constant angular acceleration of ? = 2.1 rad/s2. Assume the transmission belt does not slip on the pulley or the wheel.

EXAMPLE Description Answer Chk History Determine the linear speed of point P after wheel B has turned one revolution. (include units with answer)

Explanation / Answer

2.1 *0.13 = 0.35 * alpha of wheel

Alpha of wheel = 0.78 rad/sec^2

V ^2 = U^2 + 2*aS

V^2 = 2* 0.78 * 2*pi = 9.8

v= 3.13 m/sec
