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