Shear stress is stress from forces parallel to a surface, causing internal sliding. It's critical for joint design and fastener selection.

चरण-दर-चरण मार्गदर्शिका
- 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
हल किए गए उदाहरण
इनपुट
V = 50 kN, A = 0.01 m² (100×100 mm)
परिणाम
τ = 5 MPa (low for steel)
Safe for typical steel
सामान्य गलतियां जिनसे बचना है
- ✕Using average stress instead of accounting for concentration
- ✕Neglecting shear in fastener design
अक्सर पूछे जाने वाले प्रश्न
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.
