7-37. Determine the average normal stress in each of the 20-mm-diameter bars of the truss. Set P-40 kN. 1.5 m

F14-7. Use Mohr's circle to determine the normal stress and shear stress acting on the inclined plane AB. so kha

The uniform sign has a weight of 1500 lb and is supported by the pipe AB, which has an inner radius of 2.75 in. and an outer radius of 3.00 in. If the face of the sign is subjected to a uniform wind pressure of p = 150 lb/ft2, determine the state of stress at points Cand D. Show the results on a differential volume element located at each of these points. Neglect the thickness of the sign, and assume that it is supported along the outside edge of the pipe. 6 ft 3 ft 上 A B x 12 ft 150 lb/ft²

The beveled gear is subjected to the loads shown.Determine the stress components acting on the shaftat point B, and draw the results on a stress elementat this point.
