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.
Calculate the stress (MPa) in the steel pipe for the following
data: P = 150 kN, cross-sectional area of aluminum pipe Aa = 6000
mm2, cross-sectional area of steel pipe As = 700 mm2, modulus of
elasticity of aluminum Ea = 70 GPa, and modulus of elasticity of
steel Es = 200 GPa.
