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 `12 m`, how much force must be applied to the wheel to keep the object from falling?

Answer 1

The force is `=470.4N`

Explanation:

The load `L=(24g)N`

Radius of axle `r=24m`

Radius of wheel `R=12m`

Taking moments about the center of the axle

`F*R=L*r`

`F*12=24*g*24`

`F=(24*g*24)/12=470.4N`

The force is `F=470.4N`
