A transmission shaft is supported by bearings at A and D and loaded as shown in the figure. a. Find P required to achieve equilibrium. b. Find the reactions at the bearings. c. Sketch the V-M-T diagrams (Hint: You need to construct V and M for planes xy and xz).

5.4 For the rigid frames shown in Figure P5-4, determine (1)the nodal displacements and rotation at node 4, (2) the reactions, and (3) the forces in each element. Then check equilibrium at node 4.

A crank shaft is operated as shown in the figure. A load F1 = 9.73 N is applied and the operator %3D dz applies a load P to counter. The system is in equilibrium and all of the bearings are perfectly dz aligned such that they do not produce moments on the rotating crank. The geometry is given by, w = 7.31 [m), dl = 9.69 m], d2 = 7.57 m). 6.14 (m), d5 = 3.7 (m), %3D d1 d3 = 9.87 (m), d4 %3D F2 and h1 4.4 (m), find the following: %3D F1 Part 1.
