The structure is supported by two pins at points A and B and a roller at point F. It is subjected to a distributed load at segment CG, two point loads and a couple moment, as shown in the figure. Calculate the support reactions at points A, B, and F and the forces at the internal pins at C and D. Show all your work including a Free Body Diagram to receive full credit.
Read DetailsThe shaft is supported by a journal bearing at A and a thrust bearing at B. Determine the tension in cable CE and the reactions at A and B when a load P = 110 lb and a couple moment M = 40 lb·in is applied. Assume the bearings are properly aligned. For full credit, you must show these steps: Draw a free body diagram. Write sum of forces acting on the body. Take the sum of moments about point B.
Read DetailsA truss is supported by a pin at point F and a roller at point J. Determine the force in members AB, FG, and DG and state whether the members are in tension or compression. Show all your work and FBD(s) to receive full points.
Read DetailsA box of mass 100 kg rests on an inclined surface is subjected to a load P. The coefficient of friction between the surface and the box is equal to μs = 0.40. Find the minimum force required to move the box up on the inclined surface. You must include a FBD to receive full points. Hint: Consider two cases to determine the required load for the box to move.
