Consider the compound beam shown in Figure 1. Suppose that P1 = 790 N, P2 = 1200 N, and w = 440 N/m. Point E is located just to the left of the 790 N force. Follow the sign convention. Part D: Determine the internal normal force at point E. Part E: Determine the internal shear force at point E. Part F: Determine the internal moment at point E. Express your answer to three significant figures.
