The pendulum illustrated in the figure is composed of an AB 2 kg and a 5 kg disc. The pendulum is released from rest in the shown position and falls 0.3 m without undergoing any rotation until the end A reaches the hook S, which starts to provide a permanent connection. Determine the angular velocity of the pendulum after turning 90 °. Treat the weight of the pendulum during impact as a non-impulsive force.
1000 lb -8 ft +2ft A beam that weighs 300 lbs is supported by a roller and pin B and A respectively while being subjected to a force of 1000 lbs. If the pin at A is suddenly removed, determine the beams angular acceleration, the force exerted by support B and the horizontal acceleration just after A is removed. Assume the beam is a slender rod of negligible thickness. Please don't use angle measurements when solving. Use the 3-4-5 triangle to solve, if that makes sense. Thank you! Choutranco impgo tout

If both disks are given a clockwise angular velocity (ωA)1=(ωB)1=4.6rad/s(ωA)1=(ωB)1=4.6rad/s while the rod is held stationary and then released, determine the angular velocity of the rod after both disks have stopped spinning relative to the rod due to frictional resistance at the pins AA and BB. Motion is in the horizontal plane. Neglect friction at pin CC.
