The aluminum and steel pipes shown in the figure are fastened to rigid supports at ends A and B and to a rigid plate C at their junction. The aluminum pipe is twice as long as the steel pipe. Two equal and symmetrically placed loads P act on the plate at C
(a) Obtain formulas for the axial stresses σa and σs in the aluminum and steel pipes, respectively
b) Calculate the stresses for the following data: P= 12 k, cross-sectional area of aluminum pipe Aa 8.92 in2 , cross sectional area of steel pipe As 1.03 in2 , modulus of elasticity of aluminum Ea= 10 × 106 psi, and modulus of elasticity of steel Es = 29 ×106 psi.
