Question

An object with a mass of `6 kg` is hanging from an axle with a radius of `54 m`. If the wheel attached to the axle has a radius of `4 m`, how much force must be applied to the wheel to keep the object from falling?

Answer 1

The force is `=793.8N`

Explanation:

The load `=6gN`

Radius of axle `r=54m`

Radius of wheel `R=4m`

Taking moments about the center of the axle

`F*4=6g*54`

`F=(6g*54)/4=81g=793.8N`
