A uniform beam weighs 2.00 x 10^2 N and holds a 4.50 x 10^2 N weight. Find the magnitudes of the forces exerted on the beam by the two supports at its ends. There is a diagram shown... the beam is horizontal, and a vector is drawn from the centre of the beam, pointing down. The weight is located 1/4 of the beam's length from the right hand supporting beam. The supporting beams are represented as F1 and F2. The beam appears to be resting on the supports, with no hinges or any other thing. Any help?
