An object with a mass of 5kg is hanging from an axle with a radius of 18m. If the wheel attached to the axle has a radius of 6m, how much force must be applied to the wheel to keep the object from falling?

The force is F=147N

Explanation:

www.odicis.org

The load is L=5gN

The radius of the axle is r=18m

The radius of the wheel is R=6m

The effort is =FN

The acceleration due to gravity is g=9.8ms2

Taking moments about the center of the axle

F6=5g18

F=5g186=147N

The force is F=147N
