Cut and Count

Draw a stroke across the structure to cut it.

N V M reactions target: where moments are taken equation of condition contains internal unknowns

Grid spacing is L/2. A cut through a rigid member exposes N, V, and M. A cut through a hinge exposes two forces and no moment. A cut through a two-force bar exposes one force along the bar. Tap a green tile to keep that condition; the count in the corner updates.
