2.4-23 A trimetallic bar is uniformly compressed by an axial force P = 9 kips applied through a rigid end plate (see figure). The bar consists of a circular steel core surrounded by brass and copper tubes. The steel core has a diameter of l1.25 in., the brass tube has an outer diameter of 1.75 in., and the copper tube has an outer diameter of 2.25 in. The corresponding mod- uli of elasticity are E, = 30,000 ksi, E, = 16,000 ksi, and E. = 18,000 ksi. Calculate the compressive stresses o ,, O p, and o. in the steel, brass, and copper, respectively, due to the force P. %3| %3D Copper tube Brass tube P = 9 k Steel core 1.25 in. 1.75 in. 2.25 in.
