The forearm as an example of a third-class lever.
A lever is a straightforward machine that uses a connected constrain to turn an unbending bar about a settled rotate point/support with the motivation behind lifting a weighted load.
There are three noteworthy classes of levers, each characterized by the area of the connected compel/exertion in connection to the heap/resistance and the support. A top of the line lever has its support put between the connected compel and the heap.
A case of a top notch lever is a teeter-totter. In an inferior lever, the heap is situated between the support and the connected drive. A case of a worthless lever is a wheelbarrow.
Finally, a second rate class lever framework has its connected drive arranged between the heap and support.

Human forearm acts as a third-class lever. In a third-class lever, the input force is in between the output force and the fulcrum.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.
