Where can a first class lever be found in the body?
A first-class lever can be found in the body at the atlanto-occipital joint, where the head is balanced on top of the neck. The effort (muscle force) is applied at the back of the head when nodding forward, the fulcrum is at the joint itself, and the resistance is provided by the weight of the head.
