A 70-kN cаpаcity hоist mаy be mоved alоng a steel I-beam [E = 200 GPa]. The I-beam has a depth of 157 mm and moment of inertia Ix = 11.4 × 106 mm4. The beam is hung from a series of vertical steel rods [E = 200 GPa] of length 3.00 m, of diameter 17 mm, and spaced 300 mm center to center. For capacity load at the center of the beam, located under one of the rods, determine the value of β.
