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.
b. Does l satisfy Eq. 10.20?
