Platform with moving vertical load

Locate base resultants and distinguish full contact, kern exceedance, uplift, sliding, and complete tipping.

Advanced engineering statics simulation

Statics Stability and Tipping Suite

Rigid-body equilibrium with explicit load locations, base contact, sliding, and overturning checks; not a design-code check.

Simulation

Move a downward load across and beyond the base to observe resultant migration and contact loss.

Vertical loads contribute according to their signed horizontal offsets. Loads outside the toe can add overturning moment.

Model scope and verification

Scope: Educational rigid-body statics model using the selected geometry, stated idealizations, and displayed SI units.

Acceptance check: Check the governing equilibrium, compatibility, geometry, or limiting-condition statement before accepting the numerical result.
