Question
Chapter 11.2, Problem 1AWYK
Summary Introduction
To analyze:
The effort applied when a person sits on the edge of the desk with feet off the floor, and the resistance applied on which body part, the location of the fulcrum and the lever in the plantarflexion represent which class.
Introduction:
The muscle exerts the force on the long bones that are called levers. A fixed point on which a lever rotates is referred to as fulcrum. There are different classes of levers based on the position of the fulcrum and the resistance. It is also based on the effort that is applied in between the fulcrum and the resistance.
