Measurements should include collecting variables for use in the following equations:
- Mechanical systems—work = force × distance
- Fluid systems—work = pressure × volume
- Electrical systems—work = voltage × charge
Process/Skill Questions:
- How is work measured in mechanical, fluid, and electrical systems?
- Where would a given industry use work formulas?
- What safety precautions may be required for measuring work in mechanical, fluid, and electrical systems in a given industry?
