Problem 5.38 The cantilevered jib crane is used to support the load of 780 lb. If the trolley T can be placed anywhere between 1.5ft < z < 7.3ft, determine the maximum magnitude of reaction at the supports A and B. Note that the supports are collars that allow the crane to rotate freely about the vertical axis. The collar at B supports a force in the vertical direction, whereas the one at A does not. (Figure 1) Part A...
Problem 3: The wall crane supports a load of 700 lb with the pin at A and D. All pulleys are pin connected to the structure. The cross-sectional area of BD is 4 and the diameter for pulley B and C is 10 inches. 1) 2) 3) 4) Draw the FBDs of the pulley at E; Draw the FBD of the whole structure with the cable but without W; Find internal for NBD; Determine the average normal stress of BD...
Problem 2. Compute the reactions at each support for the beam shown. The beam weight is 85 lb/ft. A) Draw the free-body diagram (FBD) you used to calculate the reactions B) Write the equilibrium equations based on the FBD 3000 lb 750 lb/ft- 1000 lb/ft
The crane truck has a weight of 11750 lb and a center of gravity at point CG. The parking brake only locks the rear wheels of the truck, so the front wheels are free to rotate. Determine the maximum force F applied at the angle = 32.5° that can be exerted on the crane without it slipping or tipping for each of the following cases: Case 1: The static friction coefficient between the rear tires and the ground is pe...
Рис от 20 р The boom DF of the jib crane and the column DE have a uniform weight of 99 lb/ft. Take: d1 = 1 ft, d2 = 5 ft, d3 = 2.2 ft, d4 = 4 ft, d5 = 8 ft. If W = 222 lb, determine the shear force in the crane on cross section at the point A (VA) in lb. Please be mindful of the sign convention for internal loads. Selected Answer: 222 Correct Answer:...
