Solved: The following state of strain has been determined
Chapter 7, Problem 7.155(choose chapter or problem)
The following state of strain has been determined on the surfaceof a cast-iron machine part:Px 5 2720m Py 5 2400m gxy 5 1660mKnowing that E 5 69 GPa and G 5 28 GPa, determine the principalplanes and principal stresses (a) by determining the correspondingstate of plane stress [use Eq. (2.36), Eq. (2.43), and thefirst two equations of Prob. 2.72] and then using Mohrs circle forstress, (b) by using Mohrs circle for strain to determine the orientationand magnitude of the principal strains and then determinethe corresponding stresses.
