4.9 Write a computer program to read engineering constants , , , and , and then compute and print out the plane stress matrices for any material. Run your program for the properties of T300/5208 carbon/epoxy. Print out values for the fiber orientations . use your program to generate the required values ,and then plot and for values of ranging from to in increments.
