Explanation:
Given
-
The radius of the axle (r)=24cm0.24m -
The 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
