Tips for Mechanical Comprehension
- Remember: work = force × distance, and power = work ÷ time.
- Mechanical advantage = output force ÷ input force. More rope or a longer ramp means less effort.
- Meshed gears turn in opposite directions; the smaller gear turns faster.
- For levers, effort × effort arm = load × load arm.
