1) Bar A has a cross-sectional area of 2 in² and its modulus of elasticity is 10 x 10° psi. Bar B ha a cross-sectional area of 4 in² and its modulus of elasticity is 16 x 106 psi. There is a gap b=0.0 in. between the bars. A uniformly distributed load of 20 kip/in directed to the right applied to ba A, and a uniformly distributed load of 20 kip/in directed to the left applied to bar B. a. What is the value of the maximum tensile stress in bar A? Where does this stress occur? b. What is the value of the maximum tensile stress in bar B? Where does this stress occur? Bar A 10 in. 0.01 in Bar B 10 in.

From the graph find stress? and yong modulus,E?

SolveSample Problem 4.1.All remain as presented, except for the following changes.The factor ofsafety is now 2, and not 3.As Presented, the thickness of the tube is uniform. In the new one that you are solving,let the thicknessesof the top and bottom be the same,ttb, and the thicknesses of theleft and right be the same,tlr.Theheightand the width of the tube are still respectively 5 in and 3.25 in.As you make thesethickness changes,you are to keep thetotal mass of the tube unchanged. Answer the same questions (a) and (b).Explain your findings
