Let the hoist in Problem 10.12 with a capacity load of 60 kN be located under the second rod from one end. Since each sp1ing is assumed to exert an influence over a length I = 500 mm, the load acts at distance a = 750 mm from the end of the beam. Determine the maximum deflection of the beam, maximum flexural stress in the beam, maximum stress in the rods, and locations for each.

Problem 10.12

A 60-kN capacity hoist may be moved along a steel I-beam (E = 200 GPa). The I-beam has a depth of 152 mm and moment of inertia Ix = 11.0 × 106 mm4. The beam is hung from a series of vertical steel rods (E = 200 GPa) of length 2.50 m, of diameter 18.0 mm, and spaced 500 mm center to center.

a. For capacity load at the center of the beam, located under one of the rods, determine the maximum stress in the beam and the rods.
