An advertising sign located along a city street is cantilevered from a pole as shown below. The pressure due to the wind impinging on the sign is uniformly distributed over its area and equal to p = - 13.5 lb/ft² in the x- direction. The pole is fabricated from a tube with an outside diameter of do = 9.5 in. and a wall thickness of t = 0.31 in. Determine the stresses at points Cand Blocated at the base of the pole.

A compound cylinder is made by shrinking a jacket with an outer diameter of 200 mm on a hollow cylinder with diameter of 100 mm and 150 mm. When the compound cylinder is subjected to an internal pressure of 35MNm-2, the maximum circumferential stress in both cylinders is the same. Calculate the maximum stress developed at the internal diameter of the jacket.

The pipe shown has an outer diameter of 200 mm and a wall thickness of 10 mm. The length a is 1600 mm and length b is 800 mm (b is from the center of the pipe to the application of the load). There is an applied load of 25 kN as pictured and the pipe contains a static fluid pressurized at 2 MPa (this causes normal stresses in both the hoop and long directions). Determine the normal and shear stresses on the side of the pipe at point K which is coplanar with the yz-plane. K Use the following cross-sectional properties: A = 12· 103 mm² J = 54· 106 mm4 Qmax = 180 · 103 mm3 I = Iy = 27· 106 mm4 V 25 kN
