A tri-metallic bar is uniformly compressed by an axial force P = 40 kN applied through arigid end plate (see figure). The bar consists of a circular steel core surrounded by abrass and copper tubes. The steel core has a diameter of 30 mm, the brass tube has outerdiameter of 45 mm, and the copper tube has outer diameter of 60 mm. the correspondingmoduli of elasticity are E, = 210 GPa, E = 100 GPa, and Ec = 120 GPa.Copper tubeBrass tubeP= 40 kN%3DSteel core30mm45mm60mmCalculate the compressive stress in the steel core in MPa due to the force P.A. 25.11.В. 28.3Calculate the compressive stress in the brass tube in MPa.В. 8.2С. 22.4D. 21.82.A. 7.9С. 9.8D. 10.4Calculate the compressive stress in the copper tube in MPa.А. 12.5В. 14.2С. 16.4D. 17.83.
