Question
A pair of belted pulleys have diameters of 20 inch and 16 inch respectively.If the larger pulley turns at 2000 rpm, how fast will the smaller pulley turn.
Answers
Damon
speed at outer radius is the same
w1 * r1 = w 2 * r 2
where w is radians/second
so
2000 * 20/16
w1 * r1 = w 2 * r 2
where w is radians/second
so
2000 * 20/16
