if a 2 inch diameter pulley that is being driven bv an electric motor and running at 1600 rev per minute is connected by a belt to 5 inch diameter pulleys to drive a saw, what is the speed of the saw in revolutions per minute?

Question

anonymous · Answer

Circumference of a 2 inch diameter = 2pi inch
Circumference of a 5 inch diameter = 5pi inch
Now,
In 1 minute 2 inch diameter pulley rotates 1600 rev
In 1 minute 2 inch diameter pulley covers 2pi *1600 distance
In 1 minute 5 inch diameter covers 2pi *1600 distance
In 1 minute 5 inch diameter rotates (2pi*1600)/(5pi) rev
