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.
