[b]Instructions:[/b] Drag the sliders to change the normal and shear stresses acting on the element along the A- and the B-axes. The hollow red circle represents the pole for planes. The element can also be rotated by +/- 45 degrees with respect to the horizontal plane by dragging the θ slider. Click the reset icon located at top right-hand corner to revert back to default stresses and inclination.

Sign Convention: Compressive normal stresses are positive. Anti-clockwise shear stresses are positive.[br][br][Made using Geogebra by Jit Sharma. All rights reserved.]
