Describe how third-class levers operate in terms of force moved and speed of movement. Provide an example of a third-class lever
What will be an ideal response?
Third-class levers have a mechanical disadvantage in terms of force. The fulcrum in a third-class lever is located closer to the applied force and farther from the load moved. Although third-class levers are disadvantaged in terms of force, they produce a speedy movement. An example of a third-class lever is the biceps brachii muscle. The fulcrum is at the elbow joint and the load of weight is the forearm and hand. The contraction of the biceps brachii muscle is the force that moves the forearm and hand.
