📌 Note

Single-column frame treated as cantilever: M=F·e; σ=M/W; δ=F·L³/(3EI). Section W=b·h²/6, I=b·h³/12.

Combined σ = F/A + M/W on outer fibre. Stability: λ=2L/i, i=h/√12; λ>λ₁ use Euler F_cr=π²EI/(2L)², else σ_cr=σs(1−λ²/λ₁²/0.65).

σ_eq=√(σ²+3τ²), τ≈1.5·F/A; verticality δ/L ≤ 1‰ keeps slide square to the base.
