The cantilever beam is subjected to a concentrated load P. The cross-sectional dimensions of the rectangular tube shape are shown in the second figure. Assume b = 133 mm, d = 207 mm, y = 62 mm, yk = 37 mm and t = 6 mm. (a) Compute the value of Q that is associated with point H, which is located 62 mm above the centroid of the rectangular tube shape. (b) If the allowable shear stress for the rectangular tube shape is 117 MPa, determine the maximum concentrated load P that can be applied to the cantilever beam. Answers: (a) Q = (b) P = i i P Z mm³. kN. ун Ук H K b t (typ.)

3. For the given state of stress, determine the principal planes, the principal stresses, the max shear stress. You must use Mohr's Circle. 20 MPa 32 MPa 55 MPa

30 mm C A B 150 mm M 150 mm 300 mm 30 mm - determine the bending stress developed at points A, B, and C. Sketch the bending stress distribution on the cross section. - Assume that the cross-section has a moment of inertia about the neutral axis of 1.907 x 10-4 m². - Assume that the neutral axis is located 97.5 mm from the bottom of the cross-section - Assume the internal bending moment M = 61.4 kN.m
