Shear stress is stress from forces parallel to a surface, causing internal sliding. It's critical for joint design and fastener selection.
Fórmula
Calculate: τ = V/A where V is shear force and A is area
- V
- V value — Variable used in the calculation
- A
- A value — Variable used in the calculation
Guía paso a paso
- 1Calculate: τ = V/A where V is shear force and A is area
- 2For beams: τ = 1.5V/A (rectangular cross-section)
- 3Results show stress intensity and safety margins
Ejemplos resueltos
Entrada
V = 50 kN, A = 0.01 m² (100×100 mm)
Resultado
τ = 5 MPa (low for steel)
Safe for typical steel
Errores comunes a evitar
- ✕Using average stress instead of accounting for concentration
- ✕Neglecting shear in fastener design
Preguntas frecuentes
How is shear stress different from normal stress?
Normal stress acts perpendicular to surface, shear acts parallel. Materials handle shear differently.
Where is shear stress highest in a beam?
Maximum shear occurs at the supports; minimum (zero) at points of zero shear force.
