(a) Determine the number of revolutions per minute of the saw.

(b) How does crossing the belt affect the saw in relation to the motor?

(c) Let L be the total length of the belt. Write L as a function of ?, where ? is measured in radians.

## Homework Equations

## The Attempt at a Solution

a) 3400 revs/min

b) it increases the angular velocity of the saw?

c)

I used the formula for circumference and arc length to find the length of the belt around both pulleys, but I don't know how to get the length of the belt that is not around the pulleys in terms of phi.

I don't know if I'm asking for too much but please, don't give the answer, just a hint.

Thank You
