Question 8

A horizontal uniform beam of length 6L6L6L and weight WWW is supported at both ends. An object weighing 3W3W3W is placed on the beam at a distance of 2L2L2L from the right end, as shown in the diagram below. A horizontal uniform beam of length 6L is supported by vertical normal reaction forces N_1 at the left end and N_2 at the right end. A downward arrow representing the object of weight 3W is positioned on the beam at a distance of 2L from the right end. The center of mass of the beam is at the midpoint 3L from both ends. What are the magnitudes of the normal reactions N1N_1N1​ and N2N_2N2​ on the supports at the ends of the beam?
