The following table gives the approximate values of the static coefficient of friction 1 for various materials.

Materials ................................ µ
Metal on metal .................... 0.20
Wood on wood .................... 0.35
Metal on wood ..................... 0.40
Rubber on concrete ............. 0.70

To start a weight W moving on a horizontal surface, you must push with a force F, where F = µw. Write a MATLAB program that uses the switch structure to compute the force F. The program should accept as input the value of W and the type of materials.
