Example Calculations
Example 1: Torque Calculation
If a mechanic applies 50 pounds of force on a wrench that is 2 feet long, the torque produced is 100 foot-pounds. This helps ensure bolts are tightened to manufacturer specifications.
Example 2: Work/Energy Calculation
Applying a force to move an object over a distance calculates work done, useful in construction and lifting tasks.
Example 3: Kinetic Energy Calculation
An object with known mass and velocity produces kinetic energy measured in foot-pounds, helping analyze motion impact or stopping force.
Example 4: Unit Conversion
If you already know energy in joules or newton-meters, the conversion mode instantly converts it into foot-pounds and other units.
