Plane stress element

A small 2D plane-stress differential element shown front-on as a thin square or slightly rectangular flat plate aligned with the x and y directions, or optionally rotated as a square element for labeling. It has a clean black outline and white or pale gray fill, with clearly defined faces. Opposite faces carry normal stress arrows acting perpendicular to the edges and equal shear stress arrows acting tangentially along the edges. The arrows indicate normal and shear loading such as sigma_x, sigma_y, and tau_xy, with distinct directions on each edge in a textbook engineering-diagram style.
