F ΔΙ Ex σΞ == σ= Εε v = E = 2G(1 + v) A。 Ez Ez 1) A cylindrical rod of steel, having yield strength of 290 MPa, is to be subjected to a load of 8000 N. The elastic modulus is 207 GPa and Poisson's ratio is 0.3. a. If the length of the rod is 400mm, what must be the initial diameter for an elongation of 0.35mm? (3 points) b. What is the corresponding change in diameter under this loading? (3 points) c. Is there any plastic deformation? YES / NO Circle correct answer (2 points)
