Question

The 1000 kg mass is supported by a plate which is sitting on a column composed of two bars. The outer tube is bar 1, with E1 90 GPa and A1 200 mm2. The solid inner core is bar 2, with A2 = 100 m2m2 a) Find the average normal stress in each bar and determine the deflection of point A, if bar 2 is made from Red Brass C83600.
