Three tensile tests were carried out on an aluminium bar. In each test the strain was measured at the same values of stress. The results were Stress (MPa) 24.27 44.98 69.87 84.57 103.54 119.28 138.46 152.54 181.94 Strain 0.325 0.479 0.856 0.987 1.357 1.689 1.954 2.356 2.765 where the units of strain are mm/m. Calculate coefficients a and b in y= a sin(x) + b cos(x) to be a least squares fit to the data in the table. Estimate the modulus of elasticity of the bar (modulus of elasticity = stress/strain).
