It is important to consider the effect of thermal expansion when building a structure that must withstand changes in temperature. For example, a metal beam will expand in hot temperatures. The additional stress could cause the structure to fail. Similarly, a material will contract in cold temperatures. The linear change in length of a material if it is allowed to freely expand is described by the following equation:

L_Δ = aL₀T_Δ

Here, L is the initial length of the material in meters, L is the displacement in meters, T is the change in temperature in Celsius, and a is a coefficient for linear expansion.

Write a program that inputs a, L_Δ, T_Δ, and the name of the material, then calculates and outputs the material’s name and the amount of linear displacement. Here are some values for a for different materials.

Aluminum	2.31 × 10-5
Copper	1.70 × 10-5
Glass	8.50 × 10-6
Steel	1.20 × 10-5
