Question

An object with a mass of `24 kg` is hanging from an axle with a radius of `6 m`. If the wheel attached to the axle has a radius of `48 m`, how much force must be applied to the wheel to keep the object from falling?

Answer 1

The force is `=29.4N`

Explanation:

The load L=(24g)N#

Radius of axle `r=6m`

Radius of wheel `R=48m`

Taking moments about the center of the axle

`F*R=L*r`

`F*48=24*g*6`

`F=(24*g*6)/48=29.4N`
