2.2 The pins on the frame at D and E each have a diameter of 0.25 in. If these pins are subjected to double shear , determine the average shear stress in each pin.
2.3 The bar has a cross-sectional area of 400 (10 -6 ) m 2 . If it is subjected to a uniform axial distributed loading along its length and to two concentrated

Unformatted text preview: loads as shown, determine the average normal stress in the bar as a function of x for 0 < x ≤ 0.5 m. 2.4 The hanger assembly is used to support a distributed loading of w = 0.8 kip/ft. Determine the average shear stress in the 0.40-in.-diameter bolt at A and the average tensile stress in rod AB, which has a diameter of 0.5 in. If the yield shear stress for the bolt is τ y = 25 ksi, and the yield tensile stress for the rod is σ y = 38 ksi, determine the factor of safety with respect to yielding in each case....
