An iron rod of length 50 cm is joined at an end to an aluminium rod of equal length to form a system. All measurements refer to 20∘C. If coefficient of linear expansion of iron and aluminium are 12×10−6/∘C and 24×10−6/∘C respectively, find average coefficient of linear expansion of composite system? |
