Solve Problem 7.2-1 for an element in plane stress subjected to
Stresses (x = - 5700 psi, (y = - 2300 psi, and Txy = 2500 psi, as shown in the figure.
Determine the stresses acting on an element oriented at an angle ( = 50° from the x axis, where the angle u is positive when counterclockwise. Show these stresses on a sketch of an element oriented at the angle (.
