An object with a mass of 5 kg5kg is hanging from an axle with a radius of 24 cm24cm. If the wheel attached to the axle has a radius of 38 cm38cm, how much work would it take to turn the wheel a length equal to the circumference of the axle?

Explanation:
Given
-
"The radius of the axle " (r) =24cm0.24mThe radius of the axle (r)=24cm0.24m -
"The mass of the object " (m) =5kgThe mass of the object (m)=5kg
We are to calculate the work done to lift the object by turning the wheel a length equal to the circumference of the axle.
Actually the work done occurs due to the lifting of the object against the gravitational pull by length
So
