For part (b). find tensile stress " " through this 0 s oross section P=42kN m/ 51:60 mm cross section Link AB, with cross section dimensions show, is used to support the end of a horizontal beam. Knowing that the load from the supported beam is P as shown, and that the pins each have a diameter of d = 26mm, determine: (a) the shear stress in the pins, (b) the stress in the cross section of the link
