A solid 0.4150 kg0.4150 kg ball rolls without slipping down a track toward a vertical loop of radius ?=0.8750 mR=0.8750 m. What minimum translational speed ?minvmin must the ball have when it is a height ?=1.347 mH=1.347 m above the bottom of the loop in order to complete the loop without falling off the track? Assume that the radius of the ball itself is much smaller than the loop radius ?R. Use ?=9.810 m/s2g=9.810 m/s2 for the acceleration due to gravity.

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
