Engineers measure and optimize engine torque output across different RPM ranges for vehicle performance, and specify precise torque values for critical fasteners.
Assembly lines use calibrated torque tools to ensure fasteners are tightened to the correct specifications, preventing both loose connections and damaged components.
Aircraft component assembly requires precise torque application to ensure structural integrity while minimizing weight.
Robot joint design and control systems rely on torque calculations to determine motor requirements and ensure precise movement.
Torque is a measure of the rotational force that causes an object to rotate around an axis. It is calculated as the product of the force and the perpendicular distance from the line of action of the force to the axis of rotation.
In engineering and physics, torque and moment of force are essentially the same concept and are often used interchangeably. However, 'torque' is more commonly used in mechanical and automotive engineering contexts, while 'moment of force' may be used more in structural engineering and statics.
To convert from newton-meters (N·m) to pound-feet (lb·ft), multiply the N·m value by 0.737562. For example, 100 N·m equals approximately 73.76 lb·ft.
Torque in automotive engines indicates the rotational force available to move the vehicle. Higher torque at lower RPM provides better acceleration and pulling power, which is important for towing or climbing hills. It's a key specification alongside horsepower that helps consumers understand vehicle performance characteristics.
Power (P) is related to torque (τ) and angular velocity (ω) by the equation: P = τ × ω. In automotive terms, power (in watts or horsepower) equals torque (in N·m or lb·ft) multiplied by engine speed (in radians per second). This is why an engine's power typically increases with RPM even when torque might be decreasing.
