The force is $=49N$

enter image source here

The load L=(6g)N#

Radius of axle $r=5m$

Radius of wheel $R=6m$

Taking moments about the center of the axle

$F*R=L*r$

$F*6=6*g*5$

$F=(6*g*5)/6=49N$

The force is $=49N$

An object with a mass of 6 kg6 kg is hanging from an axle with a radius of 5 m5 m. If the wheel attached to the axle has a radius of 6 m6 m, how much force must be applied to the wheel to keep the object from falling?
