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

Answer 1

The force is `=396.9N`

Explanation:

The load L=(6g)N#

Radius of axle `r=54m`

Radius of wheel `R=8m`

Taking moments about the center of the axle

`F*R=L*r`

`F*8=6*g*54`

`F=(6*g*54)/8=396.9N`
