The state of plane stress at a point on a body is represented by the element below.

Angle:	$\theta = $ {{theta}} $^o $
Normal stress ($\sigma_x$):	$\sigma_x = $ {{sigmax}} $MPa $
Normal stress ($\sigma_y$):	$\sigma_y = $ {{sigmay}} $MPa $
Shear stress ($\tau_{xy}$):	$\tau_{xy} = $ {{tauxy}} $MPa $
