Mohr's Circle Lab
Mohr's circle turns plane-stress transformation into one picture. Drag the stress components to reshape the circle; rotate the plane angle θ to move around it and find the principal plane (where the shear is zero). The readouts give σ₁, σ₂, the maximum in-plane shear and the principal angle.

Rotate the plane and watch the point travel the circle. At θp = 26.6°the shear vanishes — that's the principal plane.
