Mechanical Strength Calculator

Quick strength verification for normal stress, shear, impact, and bending.

① Normal Stress (Tension/Compression)

σ = W / A

Load W (N)

Area A (mm²)

Allowable [σ] (MPa)

σ = - MPa

② Shear Stress

τ = F / A

Shear Force (N)

Area A (mm²)

Allowable [τ] (MPa)

τ = - MPa

③ Impact Loading

σ = σ_j(1+√(1+2h/δ_j))

Mass (kg)

Drop Height (mm)

Area (mm²)

Length (mm)

Modulus E (MPa)

Allowable (MPa)

σ = - MPa

④ Bending Stress

σ = M / W_z

Moment M (N·mm)

Section Modulus W_z (mm³)

Allowable (MPa)

σ = - MPa
