Question

Calculate the area expansivity and volume expansivity of a brass of area 120m and 120m respectively that assumes a new area and volume of 130m and 130m respectively when the linear expansivity is 0.00005 through a temperature of 50 degrees Celsius

Answer 1

Area expansivity = 2 * Linear expansivity

 $ß = 2 * ∝$

Area expansivity = 2 * 0.00005 = 0.0001

Volume expansivity = 3 * Linear expansivity

 $ϒ = 3*∝$

Volume expansivity = 3 * 0.00005 = 0.00015
