1) An SAE 4140 steel panel with thickness 0.10 inches is being replaced with an E-glass fiber reinforced polyester panel with equal flexural stiffness. Calculate the weight and cost differences between the panels. Assume that the stiffness is proportional to Et3, where E is the modulus and t is the panel thickness. Modulus (ksi) Density (lb/in) Cost ($/lb) Steel 30 0.284 0.2 Composite 3 0.067 1.4 1) An SAE 4140 steel panel with thickness 0.10 inches is being replaced with an E-glass fiber reinforced polyester panel with equal flexural stiffness.
