A structural steel wide-flange shape [E = 240 GPa; I = 201 × 106 mm4] is loaded and supported as shown. The beam is supported at B by a 20-mm-diameter solid aluminum [E = 78 GPa] rod. After a concentrated load of 40 kN is applied to the tip of the cantilever, determine the force produced in the aluminum rod. Assume the length between B and C is decreased by a factor of 5π.

Assume that M = 161 kN-m and that EI = 5.0 × 1010 kN-mm2 is constant. Determine the concentrated downward force P required to make the total beam deflection at B equal to zero. Assume both lengths are increased by a factor of 25π.
