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
