Determine the magnitude of acceleration of point
Mechanical Engineering
1. At the instant vA = 5 rad >s, pulley A is given an angular acceleration a = (0.8u) rad >s2, where u is in radians. Determine the magnitude of acceleration of point B on pulley C when A rotates 3 revolutions. Pulley C has an inner hub which is fixed to its outer one and turns with it.
2. At the instant vA = 5 rad> s, pulley A is given a constant angular acceleration aA= 6 rad> s2. Determine the magnitude of acceleration of point B on pulley C when Arotates 2 revolutions. Pulley C has an inner hub which is fixed to its outer one and turns with it.
3. The power of a bus engine is transmitted using the belt-and-pulley arrangement shown. If the engine turns pulley A at vA = (20t + 40) rad> s, where t is in seconds, determine the angular velocities of the generator pulley B and the air-conditioning pulley C when t = 3 s.
