Answer (3)
If the pulley rotates at a rate of 3 revolutions per second, then the period T of movement is 3 1 s
a) calculate the angular velocity:
ω = T 2 π ω = 3 1 2 π = 6 π r a d / s
b) calculate the linear velocity:
v = T 2 π R = 3 1 2 π .8 = 24 π in / s ≈ 75 , 36 in / s
Remember: 1 in/s = 300 ft/h
So, 75,36 in/s = 22,608 ft/h
The angular velocity of the pulley is approximately 3.77 rad/sec, and the linear velocity is approximately 9036 ft/hr.
