Statics Stability and Tipping Suite

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

Check base eccentricity, middle-third contact, sliding, and overturning for a centered block weight.

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

Concept question: Predict the base-resultant eccentricity.

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.
