3. Consider the composite aluminum shell with an internal steel core subjected to a 150 # axial force. If the diameter of the aluminum shell is 3 inches and the diameter of the steel core is 0.75 inches, what is the force in each piece?
(use E =29(106) for steel core and E =10(106) for the aluminum shell)
