The angular speed of wheel A is increased from rest at a constant rate of 2.39 rad/s2. Find the time needed for wheel C to reach an angular speed of 147 rev/min, assuming the belt does not slip. (Hint:If the belt does not slip, the linear speeds at the two rims must be equal.) 006 041 050 062 Review Score Review Results by Study Number the tolerance is +/-2% Click if you would like to Show Work for this question: Units Open Show Work By accessing this Question Assistance, you will learn while you earn points based on the Point Potential Policy set by your

Explanation / Answer

Angular accleration will be same for both wheels

So ac = 2.39 rad/sec^2

Wf = 147 rev/min = 147*2*3.14/60 = 15.39 rad/sec

Wf = ac* t

t = 15.39/2.39 = 6.44 sec (ans)
