A bucket of water with total mass 23 kg is attached to a rope, which in turn, is wound around a 0.050-m radius cylinder at the top of a well. A crank with a turning radius of 0.25 m is attached to the end of the cylinder. What minimum force directed perpendicular to the crank handle is required to just raise the bucket? (Assume the rope’s mass is negligible, that cylinder turns on frictionless bearings, and that g = 9.8 m/s2.)

Here is the answer for the question – A bucket of water with total mass 23 kg is attached to a rope, which in turn, is wound around a 0.050-m radius cylinder at the top of a well. A crank with a turning radius of 0.25 m is attached to the end of the cylinder. What minimum force directed perpendicular to the crank handle is required to just raise the bucket? (Assume the rope’s mass is negligible, that cylinder turns on frictionless bearings, and that g = 9.8 m/s2.). You’ll find the correct answer below

A crank with a turning radius of 0.25 m is attached to the end of the cylinder. What minimum force directed perpendicular to the crank handle is required to just raise the bucket? (Assume the rope’s mass is negligible, that cylinder turns on frictionless bearings, and that g = 9.8 m/s2.)

The Correct Answer is

45 N

Reason Explained

45 N is correct for A bucket of water with total mass 23 kg is attached to a rope, which in turn, is wound around a 0.050-m radius cylinder at the top of a well. A crank with a turning radius of 0.25 m is attached to the end of the cylinder. What minimum force directed perpendicular to the crank handle is required to just raise the bucket? (Assume the rope’s mass is negligible, that cylinder turns on frictionless bearings, and that g = 9.8 m/s2.)
