A tensile test was performed on a metal specimen with a diameter of 1/2 inch and a gage length (the length over which the elongation is meas- ured) of 4 inches. The data were plotted on a load-displacement graph, P vs. AL. A best-fit line was drawn through the points, and the slope of the straight-line portion was calculated to be P/AL = 1392 kips/in. What is the modulus of elasticity? BI

An engine part is being tested with a load of 65 000 lb. The allowable tensile stress is 10000 psi ,modulus of elasticity 40×106 psi . If the original length of specimen is 40 inches with elongation not exceeding 0.0155 inches, what diameter of the specimen is rejected.
tensile test uses a circular test specimen that has a gage length of 50 mm and diameter = 20 mm. During the test the specimen yields under a load of 100,000 N. The corresponding gage length = 50.5 mm. This is the 0.2% yield point. The maximum load of 180,000 N is reached at a gage length = 65 mm. Determine (a) yield strength, (b) modulus of elasticity, and (c) tensile strength. (d) If fracture occurs at a gage length of 73 mm, determine the ductility. i need clear ans by hand and solve very very fast in 20 min and thank you | DYBALA
