Keyway Stress Simulator
Evaluate shear and crushing stresses in parallel shaft keys. Compare operating stress against material limits, run an automated torque sweep, and analyze safety factors.

Analytical Keyway Model
Force on Key (F)
F = 2 * T / d
Shear Stress (τ)
τ = F / (w * L) = 2 * T / (d * w * L)
Crushing Stress (σ_c)
σ_c = F / (h/2 * L) = 4 * T / (d * h * L)
Factor of Safety (FoS)
FoS_shear = τ_allow / τ, FoS_crush = σ_allow / σ_c
Material allowable limits: Shear = 80 MPa, Crushing = 160 MPa.
Design is safe: stresses are within allowable limits for the selected key material.
