To solve the problems below, you will need to know the average coefficient of linear expansion, a, which differs for different materials. We define L to be the length of the object, and a to be the fractional change per unit length for a temperature change of 1°C. For aluminum, α = 24 × 10-6/°C, and for steel, a = 11 × 10-6/°C. The change in length ΔL of a material is given by ΔL = LαΔT. Consider a bar 1 m long that expands 0.6 cm when heated. Show that, when similarly heated, a 100-m bar of the same material becomes 100.6 m long.
