Lever MA formula
MA = dE/dL
What is a Class 1 Lever? Provide examples.
A Class 1 lever is when the FULCRUM is in between the effort and load. E.g., scissors and seesaws.
What is a Class 2 Lever? Provide examples.
A Class 2 Lever is when the LOAD is in between the effort and fulcrum. E.g., wheelbarrows.
What is a Class 3 Lever? Provide examples.
A Class 3 Lever is when the EFFORT is in between the fulcrum and load. E.g., shovels and tweezers.
What is dE?
The dE is the Effort Distance. It measures the space between the fulcrum and the place where force is applied. In a Class 3 Lever it is always the shorter distance.
What is dL?
The dL is the Effort Load. It measures the space between the fulcrum and the load. In a Class 3 Lever it is always the longer distance.
