Problem $4$:

A uniaxial tensile test was performed on a steel rod with a radius of $14$ mm $.$ An extensimeter with a length of $105$ mm was used. Given the tensile test data provided in Table $1,$ plot a stress vs strain diagram and identify the following:

a$)$ Yield strength

b$)$ Ultimate strength

c$)$ Elastic modulus

d$)$ Point of rupture
