Five distinct dry-friction models with explicit assumptions and scenario-specific free-body diagrams.
Solve a limiting-equilibrium ladder case with upward wall friction fully mobilized, then check the floor-friction capacity.
The rough-wall ladder is closed by assuming upward wall friction is fully mobilized; the floor demand is then checked against its capacity.
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.
