Let the curved beams in Problem 10.16 be made of an aluminum alloy (E = 72.0 GPa). Determine the maximum stress in the long beam and curved beams.

Problem 10.16

A long 40-mm diameter steel beam (E = 200 GPa) is supported by a number of semicircular curved beams. (See end view in Figure P10.16.) The curved beams are spaced along the beam with spacing l = 550 mm. Each curved beam is made of steel, has a circular cross section of diameter 30 mm, and has a radius of curvature R = 300 mm. A load P = 3.00 kN is applied to the center of the long beam located at one of the curved beams. Determine the maximum stress in the long beam and curved beams.
