A mechanic exerts 50 N of force on a pulley system to lift a 1000 N engine.
- Calculate the Mechanical Advantage of that pulley system, showing your GUESSwork.
- If the engine is lifted 1.0 meters up, how much rope does the mechanic have to pull through?
- Can you think of any reasons that the mechanical advantage you calculated might be different from what happens in the real work? Explain.
Learning Goal: Understand mechanical advantage and efficiency.
Today:
- Discuss Mechanical Advantage and Efficiency
- Begin practice work.
