A bucket filled with water has a mass of 23 kg and is attached to a rope,which in turn,is wound around a 0.080-m radius cylinder at the top of a well.What torque does the weight of water and bucket produce on the cylinder if the cylinder is not permitted to rotate? (g = 9.8 m/s²) A) 34 N·m B) 18 N·m C) 11 N·m D) 36 N·m

Question

The torque produced by the weight of the bucket and water is given by the formula: torque = force x lever arm. The force is equal to the weight of the bucket and water, which is 23 kg x 9.8 m/s^2 = 225.4 N. The lever arm is the radius of the cylinder, which is 0.080 m. Therefore, torque = 225.4 N x 0.080 m = 18 N·m. The correct choice is B.
