3. Write a computer program that reads the engineering constants E1, E2, 712 and G12, computes, and prints the 3 x 3 plane stress matrices [S], [2], [S]xy and [Q]xy for any material. Run your program for the properties of AS/3501 graphite/epoxy and print out the matrices for the fiber orientations 0, 90, -45, and +45. Also use your program to plot Ex, Ey, Gxy, Vxy, 1/xs and is for values of Oranging from 0 to 90. 3.
