A 1500 mm long composite bar consists of aluminum and steel as shown. The cross-sectional area of the aluminum bar is twice that of the steel bar. If the assembly is exposed to an axial tensile load of 250 kN, determine the lengths of each of the components if the elongation of the aluminum is the same with that of the steel. The modulus of elasticity of steel E = 200 GPa and for the aluminum is one-third of the steel.

A 1500 mm long composite bar consists of aluminum
and steel as shown. The cross-sectional area of the
aluminum bar is twice that of the steel bar. If the
assembly is exposed to an axial tensile load of 250 kN,
determine the lengths of each of the components if the
elongation of the aluminum is the same with that of the
steel. The modulus of elasticity of steel E = 200 GPa and
for the aluminum is one-third of the steel.
