In Figure (a), a uniform 30.9 kg beam is centered over two rollers. Vertical lines across the beam mark off equal lengths. Two of the lines are centered over the rollers; a 9.55 kg package of tamale is centered over roller B. What are the magnitudes of the forces on the beam from (a) roller A and (b) roller B? The beam is then rolled to the left until the right-hand end is centered over roller B (Figure (b)). What now are the magnitudes of the forces on the beam from (c) roller A and (d) roller B? Next, the beam is rolled
