For many materials, the stress-strain curve can be written by the Ramberg-Osgood equation presented below, where the parameters E, k and n are obtained from the stress-strain diagram of a given material. Considering the s-e diagram shown in the figure for a certain material, determine E, k and n and obtain the formula for the curve.

Determine the elastic modulus and the yield strength for the material having the stress-strain curve shown. Use the 0.2% offset method. 1600 1400 1200 E 1000 800 600 400 200 0.5 1 1.5 2 Strain, percent Elastic modulus: (Express your answer in whole numbers.) E = ksi Yield strength: (Express your answer using three significant figures.) Sy = ksi Stress, psi

An aluminum alloy [E = 70 GPa; v = 0.33; a = 23.0x10-6/°C] pipe is subjected to a tensile load P. The pipe has an outside diameter of D = 280 mm, a cross-sectional area of A = 7550 mm², and a length of L = 9.5 m. The initial longitudinal normal strain in the pipe is zero. After load P is applied and the temperature of the pipe has been increased by AT = 40°C, the longitudinal normal strain in the pipe is found to be 2260 με. Calculate the magnitude of load P. Answer: P = M. L kN D P
