• Optical equipment: μN⋅m range

🔧 Torque Fundamentals

Definition: Rotational force, tendency to cause rotation (τ = r × F)

Right-Hand Rule: Curl fingers in rotation direction, thumb points along torque vector

Units: Force × Distance (N⋅m, lb⋅ft, etc.)

Angular Acceleration: τ = I × α (I = moment of inertia, α = angular acceleration)

Power Relationship: P = τ × ω (ω = angular velocity)

🚗 Automotive Applications

Engine Torque: Peak torque at specific RPM, affects acceleration

Torque Specifications: Proper fastener tightening prevents failure

Torque Wrench Use: Click-type, beam-type, digital types available

Sequence Matters: Star pattern for wheel lugs, head bolts

Thread Pitch Effect: Fine threads require less torque than coarse

⚙️ Mechanical Engineering

Fastener Design: Torque specifications based on material strength

Machine Design: Torque requirements for motors, gearboxes

Shaft Design: Torsional stress τ = T×r/J (T=torque, r=radius, J=polar moment)

Gear Trains: Torque multiplication through gear ratios

Clutch Design: Torque transmission capacity

🔬 Measurement & Testing

Torque Wrenches: Click, beam, dial, digital types

Torque Sensors: Strain gauge, optical, magnetic types

Calibration: Regular calibration ensures accuracy

Test Methods: Static, dynamic, continuous monitoring

Accuracy Classes: ±1%, ±2%, ±4% typical for different applications

⚠️ Safety Considerations

Over-torquing: Can strip threads, break fasteners, damage components

Under-torquing: Can cause loosening, joint failure, safety hazards

Torque Sequence: Follow manufacturer specified tightening patterns

Tool Maintenance: Calibrate torque tools regularly for accuracy

Environmental Factors: Temperature, lubrication affect torque requirements

⚡ Power & Torque Relationship

Power Formula: P = τ × ω (Power = Torque × Angular velocity)

Motor Characteristics: High torque at low RPM vs high speed motors

Gearing Effects: Torque multiplication reduces speed, increases torque

Efficiency: Real systems have losses, reducing available torque

🏭 Industrial Applications

Assembly Lines: Automated torque control for consistent quality

Quality Control: Torque testing ensures product reliability

Maintenance: Proper torque specifications prevent equipment failure

Documentation: Torque records for traceability and compliance
