Please help! A 10\" diameter pulley rotates at 1200 rpm. What is the linear velocity of a point I its circumference? That\'s all of the information given.
Solution
number of revolutions in one sec = 1200/60 = 20 revolution per sec
angular velocity = 2*pi*20 rad per sec.
Linear velocity = r * w = 5*2*3.14*20 = 628 inch per sec.
