Answer #1

There are 3 types of lever: 1st class, 2nd class and 3rd class.

In first class lever, fulcrum is located between the effort (applied force) and the load. In second class lever, load is located between the effort and the fulcrum and in third class, effort is between the load and the fulcrum.

In diagram 1 of face skull, the point A is resistance or load, B fulcrum and C is effort or applied force.

In diagram 2 of leg, point D is fulcrum, E is load and F is applied force.

In diagram 3 of arm, G is fulcrum, H is applied force and I is load.
