The uniform 24‐m mast weighs 300 kg and is hinged at its lower end to a fixed support at o. if the winch c develops a starting torque of 1300 n · m, calculate the total force supported by the pin at o as the mast begins to lift off its support at b. also find the corresponding angular acceleration α of the mast. the cable at a is horizontal, and the mass of the pulleys and winch is negligible.

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
