An electrical worker stands in the bucket that hangs from a pin at end D of the boom of the cherry picker in Fig. 1. The worker and bucket together weigh a total of 300 lb. Between A and C the boom weighs 1.1 Ib/in., and between C and D it weighs 0.8 lb/in. Assume that AC and CD are uniform beams. Determine the normal force, the transverse shear force, and the bending moment that act at cross section E, midway between A and B. Bucket Fig. 1 (a) "Bucket truck."
