A rod with a diameter of 13 mm and a length of 50 mm is subjected to a force of 50 kN. The diameter is reduced to 12.99265 mm. Determine: a. The modulus of elasticity. Answer: 200 GPa. b. Poisson's ratio. Answer: ν = 0.30 c. Shear modulus. Answer: G = 76.92 GPa. d. The deformation of the rod. Answer: δx = 0.09415 mm. Recommendation: Obtain the modulus of elasticity using the slope of the straight line.
