1. What is Shear Stress on Surface of Shaft?

Shear stress on surface of shaft is force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. It's a critical parameter in mechanical engineering for analyzing shaft strength and durability.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Shear stress} = \frac{16 \times \text{Torque}}{\pi \times \text{Diameter}} \]

Where:

Torque - Torque exerted on wheel (N·m)
Diameter - Diameter of the shaft (m)
π - Mathematical constant (approximately 3.14159)

Explanation: This formula calculates the maximum shear stress on the surface of a circular shaft subjected to torsion.

3. Importance of Shear Stress Calculation

Details: Calculating shear stress is crucial for designing shafts that can withstand torsional loads without failure. It helps engineers determine appropriate shaft dimensions and materials for various applications.

4. Using the Calculator

Tips: Enter torque in Newton-meters and diameter in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for input values?
A: Use Newton-meters (N·m) for torque and meters (m) for diameter to get results in Pascals (Pa).

Q2: Why is the constant 16 used in the formula?
A: The constant 16 comes from the polar moment of inertia formula for a solid circular cross-section (J = πd⁴/32) and the torsion formula (τ = Tr/J).

Q3: Does this formula work for hollow shafts?
A: No, this specific formula is for solid circular shafts. Hollow shafts require a different formula that accounts for inner and outer diameters.

Q4: What is a typical safe shear stress value for steel shafts?
A: For mild steel, typical allowable shear stress ranges from 40-60 MPa, but this varies based on the specific steel grade and safety factors.

Q5: Can this calculator be used for dynamic loading conditions?
A: This calculator provides static shear stress values. For dynamic or fatigue loading, additional factors and safety margins should be considered.
