A bell-ringer hits a massive bell using a 20-kg cylindrical log. The log is supported by two cords that behave like a rod. He normally uses a 200-N force P, at 60° with respect to the log, to push the log towards the bell. Assuming the two supports have negligible mass, determine the(a) normal and tangential accelerations of the log, and the (b) force developed at each support, at the instant when the cords are vertical and the angular velocity of the log is w = 6 rad/s, cw. P = 200 N w = 6 rad/s 1.5m e = 60A 0.5m. 0.75m 0.75m 0.5m
