ATTENTION: Fоr this multiple chоice questiоn, you MUST show your work in the scrаtch pаper in order to get аny credit. Figure below shows the tensile stress-strain curve of a cylindrical rod made from a steel alloy. The rod has a cross-section of 1 x 10-3 m2. What is the maximum load that this rod can support, yet still recover its initial shape when the load is removed? What is the value of elastic modulus? What is the value of modulus of resilience? The rod has an initial length of 0.5 m. What is the new length of the rod once it is placed under a static tensile stress of 550 MPa? What is the value of ductility in percent elongation? NOTE: As long as you show your work/calculations, reading different values from the axes will not lose you any credits.
