PROBLEM 2A tri metallic bar is uniformly compressed by an axial force P=12kN applied through a rigid end plate. The bar consists of a circular steel core surrounded by brass and copper tubes. The steel core has a diameter 10mm, the brass tube has an oute diameter of 15mm and the copper tube has an outer diameter of 20mm. E for steel =210Gpa, E for brass =100GPa and E for copper is 120GPa. Calculate the compressive stress of each metal due to force P.
A scuba tank is being designed for an internal pressure of 1600 psi with a factor of safety of 2.0 with respect to yielding.
