Problem 1 Given the following structures (please note that those structures are the ones you have already solved in HW 1): 1. Find the expressions of the moment (M), axial (N), and shear (S) diagrams as functions of z. 2. Plot the moment (M), axial (N), and shear (S) diagrams. a) c) b) F = 1000 N F = 500 N M 300 000 N mm F2 = 600 N a = 750 mm b = 1000 mm M = 300 000 N mm d) F = 500 N F = 600 N a = 600 mm b = 1000 mm a = 600 mm b = 1000 mm F2 = 600 N F = 1000 N M =200 000 Nmm -250 mm b=1000 mm c=250 mm Figure 1: Schematics problem 1.
