Define the slope of the curve (modulus of elasticity) of the material up to the proportional limit. Stress sigma is plotted as a function of strain epsilon. The strain is measured from 0 to 0. 0045 inches per inch on the x axis. The stress is measured from 0 to 80 kilopounds per square inch on the y axis. The stress linearly increases from the origin to approximately 33 kilopounds per square inch at 0. 0011 inches per inch. Then it increases at a slightly decreasing rate to approximately 37 kilopounds per square inch at 0. 0027 inches per inch and remains at this value until 0. 0045 inches per inch. Express your answer in kilopounds per square inch to three significant figures. View available hint(s)for part b activate to select the appropriates symbol from the following choices.
