Acompany gives you a 50mmx6mm (wxh) test coupon that is 0.5 meters in length. they tell you that from their testing, the modulus of rigidity for this material is 80 gpa, and that the yield strength is 300 mpa. they ask you to predict the lateral deformation (width and height) of a 2cmx4cm (wxh) bar they will be using in a design that will be subjected to a 40kn axial tensile load. you test your coupon using a simple tension test, and note that during the test, when the material is within the proportional elastic limit, the coupon deforms 0.012mm when subjected to a load of 1512 n. how much will the bar deform?
