As shown, a roller at point A and a pin at point B support a uniform beam that has a mass 32.0 kg . The beam is subjected to the forces F1 = 36.0 N and F2 = 63.0 N. The dimensions are L1 = 0.950m and L2 = 2.30m . (Part B figure) What are the magnitudes FA and FB of the reaction forces FA and FB at points A and B, respectively? The beam's height and width are negligible.1118668_004.jpg
