4. A round A36 steel test specimen has a diameter of do of 22mm and a gauge length of Lo 175mm. Take Oy = 250 MPa. (20 pts) a] If a force of 70 kN elongates the length by 1mm, what is the engineering stress and strain in the specimen at this load? (5 pt) b] What is the factor of safety against yielding? (5 pt) b] Is the specimen behaving elastically? How do you know? (5 pt) c] Assuming a linear stress-strain relationship, calculate the modulus of elasticity for this material. (5 pt)
