SUMMARY
The discussion focuses on calculating the torque exerted by a frictionless pulley system involving a bucket of water. The pulley has a radius of 0.41 m, and the bucket, with a mass of 1.53 kg, falls for 2.04 seconds, covering a distance of 2.87 m. The torque (t) is calculated using the formula t = F * R, where F is the tension in the rope, derived from the weight of the bucket and the acceleration due to gravity (9.81 m/s²). The key takeaway is that the tension in the rope, not the weight of the bucket, directly exerts the torque on the pulley.
