Getting measurements from Figure , determine approximate values of the following items for steel with different carbon contents. Use one system of units only as specified by the instructor.a. Yield stressb. Ultimate strengthc. Strain at failured. Effect on modulus of elasticitye. Approximate toughness. Curves may be approximated with a series of straight lines.f. Comment on the effect of increasing carbon content on items a through e above.

Determine the compressive force (in lb) in the bars shown after a temperature rise of 173°F if d = 0.015 in. Round off the final answer to five decimal places. Use the following data: Bronze              Aluminum A = 2.24 sq. in          A = 2.78 sq. in  E = 14959726 psi            E = 10594540 psi L = 12.5 in            L = 16.6 in α = 11.61 x 10-6/ °F      α = 12.67 x 10-6/°F

Compute the value the shear modulus G of steel whose modulus of elasticity E is 200 GPa and poisson's ratio is 0.30.
