A disk with a radius of 4.5 m has a 100-N force applied to its outer edge at two different angles. The disk has a rotational inertia of 165 kg m2.
a. What is the magnitude of the torque applied to the disk in case 1?
b. What is the magnitude of the torque applied to the disk n case 2?
c. Assuming the force on the disk is constant in each case, what is the magnitude of the angular acceleration applied to the disk in each case?
d. Which case is a more effective way of spinning the disk?
