Answer 1

The elbow is considered a third class lever because the effort is applied closer to the fulcrum than the load 12.

In a third-class lever, the effort is applied between the fulcrum and the load. The biceps muscle, which originates from the scapula, inserts at the proximal part of the elbow. As the biceps contracts, it rotates the forearm about the elbow joint, bringing it closer to the body. This motion is called elbow flexion 1.

Therefore, Option B: the effort is applied closer to the fulcrum than the load is the correct answer.
