A bucket filled with water has a mass of 53 kg and is hanging from a rope that is wound around a 0.05 m radius stationary cylinder. If the cylinder does not rotate and the bucket hangs straight down, what is the magnitude of the torque the bucket produces around the center of the cylinder

26 Nm

Explanation:

we use the formula for torque:

where is the radius and is the force applied.

The force that the bucket exerts on the cylinder is equal to the weight of the bucket  (since the bucket is not moving this is the only force present), where m is the mass and g is the acceleration due to gravity.

So the force is:

And substituting this in the equation for the torque:

substituting the values we know:

the result is:

15.3 cos 65 degrees trig

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
