Problem NO. 2. A student performed a tensile test in one of his samples, an aluminum specimen which is 0.505 inches in diameter, length L of 2 inches. A) Calculate the value of E when the load is increased by an amount of P = 2 kips, and the distance between gage marks increases by an amount of AL = 0.00196 inch. B) What is the value of ɛ if the proportional limit stress for this specimen is OPL = 45 ksi?
