Consider the frame shown. Member AB has a 3 x 1 in^2 cross-section while all other members have a 2 x 0.5 in^2 cross-section. Pins A, B, and C have a diameter of 1.25 in while pins D, E, and F have a diameter of 1 in. Note that there are two support plates at E and two members DF. Calculate: a. the average normal and shear stresses in sections a-a of member AB b. the maximum average normal stress in members AB and DF C. the average shear stress in pins A and D d. the maximum average bearing stress on member BCDE
