1. The beam below has an axial release just to the left of C. Find the axial force (N), shear (V), and moment (M) diagrams along the beam. Label all critical N, V, and M values and also the distance to points where N, V, and/or M is zero.(20%)

2. A tubular beam ACB with a length of L = 1.5 m is pin supported at its ends, A and B. A powered winch at E lifts load W below C using a cable which passes over a frictionless pulley at midlength (point D). The distance from the center of the pulley to the longitudinal axis of the tube is d = 140 mm. The cross section of the tube is square with an outer dimension of b = 15 cm, area of A = 125 cm2, and moment of inertia of I = 3385 cm4. Determine the maximum tensile and compressive stresses in the beam due to a load W = 13.5 kN.(20%)
