Question
The trimetallic composite section in Figure 4 is compressed by an axial load P = 12 kN applied through a rigid plate. The section consists of a circular steel core surrounded by 2 brass and copper shells. The steel core has a diameter of 10mm, the brass shell has an external diameter of 15mm, and the copper shell has an external diameter of 20mm. The corresponding modulus of elasticity are Ea = 210 GPa, El = 100 GPa and Ec = 120 GPa.
(a) Calculate the compressive stress σa, σl, and σc, in the steel, brass, and copper, respectively, that produces the force P.
