Problem 3 20 Points Two Tensile Tests Were Carried Out On An Aluminum Bar In Each Test The Strain Was Measured At Th 1 (63.7 KiB) Viewed 19 times

Problem 3 (20 points): Two tensile tests were carried out on an aluminum bar. In each test the strain was measured at the same values of stress. The results were: Stress (MPa) Strain (Test 1) Strain (Test 2) 34.5 0.46 0.34 69.0 0.95 1.02 103.5 1.48 1.51 Where the units of strain are mm/m. Use linear regression to estimate the modulus of elasticity of the bar (modulus of elasticity=stress/strain).
