determine:

1. The support forces in the points A, B, and D in the beams.
2. The resultant internal loadings acting on the transversal/perpendicular cross-sections at points M, N, and P. The points M, N, and P are half the respective lengths. Work with the sections AM, AN, and DP for points M, N, and P, respectively.

(solve the problem step by step, draw the free body diagram for each part, apply the equilibrium static equations)
