3 cards from this section. Quick, good the night before a test.
What is a lever?
Think about how it helps you lift things.
What is the fulcrum in a lever?
Where does the lever balance?
What is the function of a lever?
Think about how everyday tools help you lift.
True or False: The fulcrum is the load in a lever system.
Identify the function of each part of a lever.
Design a lever system to lift a 300 N stone using 75 N of effort. What type of lever will you use, and how long should the effort arm be compared to the load arm for optimal mechanical advantage?
Consider the ratio of distances from the fulcrum to each point.
A construction worker uses a lever to lift a beam weighing 500 N with 100 N of effort. Calculate the mechanical advantage and discuss its importance in construction.
Think about how this reduces fatigue in workers.
