1st class levers have the fulcrum midway between the effort and the load, the fulcrum is quite close to both the effort and the load.

What is a 2nd class lever ?
second class levers have the load between the fulcrum and the effort. this mean that a large load can be moved with relatively low effort
2 of 7
What is a 3rd class lever ?
3rd class levers have the effort placed between the fulcrum and the load. this means they can produce a larger range of movement with relatively low effort

What does "FLE - 123" mean ?
FLE (Fulcrum, Load, Effort) is which one goes in the middle of the lever. and the number is which type of lever it is. F is in the middle of 1st, L is in the middle of 2nd, E is in the middle of 3rd.

What is Mechanical Advantage ?
the distance from the load to the fulcrum is known as the load arm, while the distance from the effort arm to the fulcrum is known as the effort arm.

What is a HIGH Mechanical Advantage and what does it do ?
when a levers effort arm is longer than its load arm it has a HIGH mechanical advantage. levers with HIGH mechanical advantage can move large loads with low effort
6 of 7
What is a LOW Mechanical Advantage and what does it do ?
when a levers load arm is longer than its effort arm, it has a LOW mechanical advantage. 3rd class levers always have low mechanical advantage. they cannot lift heavy loads.
