A bar of 4340 steel has an Sy = 50 ksi. Which of these statements is true: If Sy = 50 ksi, than the normal stress in the bar is always 50 ksi. If a normal stress of 40 ksi is applied to the bar, it will undergo plastic deformation. The Sy = 50 ksi indicates bar is behaving in a brittle manner. O Any normal stress above 50 ksi will cause plastic deformation in the bar.
