A steel rod (initial diameter: 3.2 mm, initial length: 42 mm) is extended by a uniaxial tensile load of 4800 N in 120 seconds. At this load, the length of the rod is measured as 49,2 mm. Calculate the followings: (a) Stress and strain occurred on the rod at this load. (b) Initial strain rate. (c) Diameter of the rod at this load. (Yield strength : 380 MPa, Ultimate Tensile Strength: 670 MPa, Modulus of Elasticity: 210000 MPa were given for this material)
