A 300 kg beam is supported at each end. (The beam is horizontal). A 100 kg mass sits one third of the way from one end. Find the force acting upward at each end. (Please clarify when answering: Do you take the center of gravity from the main beam as l/2 and the center of the top beam as l/6? Basically taking half of each beam as their center of gravity?)
