Chapter 7, Problem 5P

Tables of material properties list density, in units of kg/m³, when the international system of units (SI) is used, and list specific weight, in units of lb/in.3, when the U.S. customary system of units is used. Write a user-defined MATLAB function that converts density to specific weight. For the function name and arguments, use [sw]=DenToSw (den). The input argument den is the density of a material in kg/m³, and the output argument sw is the specific weight in lb/in.3. Use the function in the Command Window to:

(a) Determine the specific weight of copper whose density is 8960 kg/m³.

(b) Determine the specific weight of concrete whose density is 2,340 kg/m³.
