The overhanging beam carries two concentrated loads W and a uniformly distributed load of magnitude 4W. The working stresses are 6000 psi in tension, 10 000 psi in compression, and 8000 psi in shear. (a) Show that the neutral axis of the cross section is located at d = 2.167 in. and that the moment of inertia of the cross- sectional area about the neutral axis is I = 61.55 in.4. (b) Determine the largest allowable value of W. 2 ft 4W (total load) 6 ft 2 ft 1.0 in 6 in. NA FIG. P5.84 1.0 in. -1.0 in. 6 in.
