(a) Make an isometric drawing of the crankshaft shown in Fig. 1, and place all reactions thereon that are necessary for equilibrium.
(b) Cheek CD is rectangular in cross section, 2 in. wide in the x-direction, and 3 in. deep in the z-direction. Cut the cheek midway between C and D, and show all forces and moments acting on the cut surface.
(c) Draw the element at R lying at the midpoint of the top surface of the cheek with sides parallel to the coordinate axes, and show all stresses acting. Mark directions of the axes on the sketch.
(d) Repeat part (c) for the element at S at the center of the near-side vertical surface of the cheek.
(e) Suppose the loading consists of a force of 3000 lb in the xy-plane acting to the left at A parallel to the y axis. Find the bearing reactions for the shaft. Cut the cheek midway between C and D, and show all forces and moments acting on the cut surface.
(f) Draw the element at R showing all stresses acting.
(g) Draw the element at S showing all stresses acting.
