The thin rod of the figure has a mass of 15kg and is attached to a spring of constant K = 50 N/m at one end, which has an unstretched length of 1.5 m. If the rod is released from rest in horizontal position (ø = 0°) and only conservative forces act on it, determine: a) What is the moment of inertia of the thin rod around the axis of rotation in A? b) What is the angle at which the rod is momentarily resting again? c) What is the maximum angular speed of the route? Please attach the free body diagram if necessary. Thank you!
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
