Question
The hoist pulley structure shown is rigidly attached to the wall at C. A load of sand sits on a tray hanging from the cable that passes around the 1-ft-diameter. frictionless pulley at D. The weight of the sand, can be treated as a triangular distributed load with a maximum intensity of w = 70 lb ft and a width of 1.5 ft, If a = 3.5 ft, b = 2 ft and h = 3.5 ft, determine: all forces and moments acting on member ABC the shearing stress on the cross section of the 0.45 in. diameter pin D, which is in double shear the change in length of member BE if it has a 0.2 in by 0.9 in rectangular cross-section, and a modulus of elasticity E = 30000 ksi. Hint: the overall magnitude of the triangular distributed load may be found by finding its "area." i.e. taking the "height" w times the base c divided by 2. Indicate compressive forces and deformations with negative numbers, tensile forces and deformations with positive numbers. Indicate counter-clockwise moments with positive numbers and clockwise moments with negative numbers.Explanation / Answer
