Unformatted text preview: following readings are obtained for each gauge: ε a =950(106 ), ε b =380(106 ), ε c = 220(106 ). Determine the strain components ε x , ε y , & γ xy . (15pts) Note: ε a , ε b , ε c in the solution are different from the problem, but the approach should be exactly the same. Problem 4: A short concrete cylinder having a diameter of 50mm is subjected to a torque of 500N.m and an axial compression force of 2KN. Determine if it fails according to the maximumnormalstress theory. The ultimate stress of the concrete is σ ult =28MPa. (20pts) Problem 5: express σ x’ in terms of σ x , σ y , & τ xy . Show derivation steps. (10 pts) Bonus problem : The stress at a point is shown on the element. Determine the principle stresses and the absolute maximum shear stress. (10pts)...
