Question

in a first class lever the is in between the load and effort​

Answer 1

Answer:

Levers are classified by first, second, and third class, depending upon the relations among the fulcrum, the effort, and the resistance.

First-class levers have the fulcrum in the middle, like a seesaw. Nodding the head employs a first-class lever, with the top of the spinal column as the fulcrum.

Second-class levers have a resistance in the middle, like a load in a wheel-barrow. The body acts as second-class lever when one engages in a full-body push-up. The foot is the fulcrum, the body weight is the resistance, and the effort is applied by the hands against the ground.
