Question

An object with a mass of `24 kg` is hanging from an axle with a radius of `24 m`. If the wheel attached to the axle has a radius of `1 m`, how much force must be applied to the wheel to keep the object from falling?

Answer 1

The force is `=5644.8N`

Explanation:

The load `L=(24g)N`

Radius of axle `r=24m`

Radius of wheel `R=1m`

Taking moments about the center of the axle

`F*R=L*r`

`F*1=24g*24`

`F=(24*g*24)/1=5644.8N`

The force is `F=5644.8N`
