1. A thin pole of length L = 3 m and mass 6 kg is being raised by a rope of tension 80 Newtons as shown. The left end of the pole can rotate about a pivot attached to the wall. Determine the magnitude and direction of the angular acceleration of the pole. The general steps in applying the rotational 2nd law are given below. a. Draw an extended free body diagram showing the forces on the rod and where they act. • The weight acts at the center of mass. • There must be a force at the pivot that holds that end in place. b. Determine the torque generated by each force on your FBD. Sum the torques to get the left-hand side (LHS) of the rotational 2nd law. C. Determine the moment of inertia of the pole. FBD 30° T d. Apply the rotational 2nd law to determine the magnitude and direction of angular acceleration of the pole.

A circular plate is being supported by 7 outer springs and a central spring. The outer springs are equally placed around a bolt circle. Take note that the outer springs are 2 mm shorter than the central spring. Further, a 5000- Newton force is applied at the center of the plate pushing the springs down.
