A wooden bucket ﬁlled with water has a mass
of 59 kg and is attached to a rope that is
wound around a cylinder with a radius of
0.071 m. A crank with a turning radius of
0.29 m is attached to the end of the cylinder.
What minimum force directed perpendicularly to the crank handle is required to raise
the bucket? The acceleration of gravity is
weight of bucket=50g
Now consider the crank and cylinder to be a lever.
solve for force.
