Problem $07\mathrm{.}003-$ Determine the normal and shearing stresses exerted on the oblique face of the shaded triangular element.

For the given state of stress, determine the magnitude of normal and shearing stresses exerted on the oblique face of the shaded triangular element shown. Use a method of analysis based on the equilibrium of that element. Take $Y=9$ksi.

The magnitude of normal stress exerted on the oblique face of the shaded triangular element is $|$ ksi.

The magnitude of shear stress exerted on the oblique face of the shaded triangular element is $$ ksi.
