A steel rod having a length of 50 m is suspended vertically from one end. It supports a tensile load of 250 kN at the lower end. The unit weight of the steel is 7,850 kg/m3. The allowable tensile stress for steel is 140 MPa. Use E- 200 GPa. Determine the total deformation of the steel rod?

please help answer and explain

3. The elastic portion of the stress-strain diagram for a titanium alloy used for medical implants shown. The specimen from which it was obtained has an original diameter of 10 mm and a gage length of 45 mm. If a tensile load of P = 300 kN is applied to the specimen. Take Poisson ration 0.3. a) determine specimen's new length after deformation. b) determine specimen's new diameter after deformation.
