The bar is connected to the support using a pin having a diameter of d = 1 in. If the allowable tensile stress for the bar is 1st2allow = 20 ksi, and the allowable bearing stress between the pin and the bar is 1sb2allow = 30 ksi,determine the dimensions w and t so that the gross area of the cross-section is wt = 2 in2 and the load P is a maximum. What is this maximum load? Assume the hole in the bar has the same diameter as the pin.
The cable has a specific weight g (weight/volume) and cross-sectional area A. Assuming the sag s is small so that the cable’s length is approximately L and its weight can be distributed uniformly along the horizontal axis, determinethe average normal stress in the cable at its lowest point C.
The compound wooden beam is connected together by a bolt at B. Assuming that the connections at A, B, C, and D exert only vertical forces on the beam, determine the required diameter of the bolt at B and the required outer diameter of its washers if the allowable tensile stress for the bolt is 1st2allow = 150 MPa and the allowable bearing stress for the wood is 1sb2allow = 28 MPa. Assume that the hole in the washers has the same diameter as the bolt.
