An object with a mass of 3 kg is hanging from an axle with a radius of 2 m. If the wheel attached to the axle has a radius of 1 m, how much force is needed to raise the object?

Answer:

The force is $= 58.8 N$

Explanation:

The load $= \left(3 g\right) N$

Radius of axle $r = 2 m$

Radius of wheel $R = 1 m$

Taking moments about the center of the axle

$F \cdot 1 = 3 \cdot g \cdot 2$

$F = \frac{3 \cdot g \cdot 2}{1} = 6 g = 58.8 N$
