How Can We Help? The fulcrum is still on the outside, but the load is on the other side, meaning that the effort is now in the middle. Science knowledge is based upon logical and conceptual connections between evidence and explanations.
The easier to a person using
The fulcrum is located between the load and effort.

Third class lever uses the effort in the center, while the output load is on one side, raising the load on the opposite end.
In first understand how many examples of first class lever examples of an effort and limbs.
Like the first class lever, the second class also has the fulcrum closer to the load force, so as to decrease the effort force required.
Thank you for sharing. Therefore, a force applied to a point farther from the pivot must be less than the force located at a point closer in, because power is the product of force and velocity.
