Torque, a fundamental force in mechanics, measures the rotational force applied to an object. It's expressed in foot-pounds (ft-lbs) or pound-inches (lb-in). Understanding this conversion is crucial for various applications, from tightening bolts to understanding engine power.
Formula: ft-lb = lb × feet
Example: To convert 500 lbs to ft-lbs, multiply 500 lbs by the distance in feet. Let's assume the distance is 2 feet.
ft-lb = 500 lbs × 2 feet
ft-lb = 1,000 ft-lbs
Remember: The distance must be measured in feet for accurate conversion.
Table 1: Common Torque Ranges
Application | Estimated Torque Range (ft-lbs) |
---|---|
Hand-held tools | 5 - 50 |
Automotive maintenance | 20 - 150 |
Industrial machinery | 50 - 500 |
Heavy equipment | 500 - 5,000 |
Table 2: Conversion Factors
Unit | Conversion |
---|---|
lb-in | ft-lb / 12 |
ft-lb | lb-in × 12 |
Nm | ft-lb × 0.73756 |
ft-lb | Nm × 1.35582 |
