Torque Visualization
Explanation
Torque (τ) is a measure of the force that can cause an object to rotate about an axis. It depends on three factors:
- Force (F): The applied force in newtons
- Distance (r): The distance from the pivot point to the force application point
- Angle (θ): The angle between the force vector and the lever arm
The general formula is: τ = F × r × sin(θ)
🔧 Common Torque Values
| Application | Typical Torque (N·m) | Typical Torque (lb·ft) |
|---|---|---|
| Bicycle wheel nuts | 30-50 | 22-37 |
| Car wheel lugs | 90-120 | 66-89 |
| Engine head bolts | 60-100 | 44-74 |
| Spark plugs | 20-30 | 15-22 |
| Furniture assembly | 5-15 | 3.7-11 |
| Industrial machinery | 200-500 | 148-369 |
Note: Always consult manufacturer specifications for exact torque requirements.
🔩 Torque Application Tips
Use a Torque Wrench
For critical applications, always use a calibrated torque wrench to ensure proper tightening.
Follow Patterns
When tightening multiple fasteners, follow the manufacturer's recommended sequence and tighten in stages.
Lubrication Matters
Lubricated threads require less torque than dry threads to achieve the same clamping force.
Lever Arm Length
Increasing lever arm length reduces the required force for the same torque output.
Angle Importance
Maximum torque occurs at 90°; at 0° no torque is produced regardless of force.
Check Specifications
Always verify torque specifications as under/over-tightening can cause failures.
