1. The type of lever action involved in the lifting up of heel. plz answer it​

Answer 1

Answer:

first class lever action

Explanation:

When you use the foot as a lever in walking

and running, the ankle is the pivot point and

the bones of the foot are the levers. When you

use the bones as levers in this way, they are

called first-class levers. First-class levers can

allow you to lift a heavy weight with a small amount of force. For example, first-class levers

allow you to lift your whole body weight with

the relatively small leg muscles.

A first-class lever also causes a change in the

direction of the force so that the muscles in the

back of your lower leg, which pull upward on

the back of your foot (your heel), make the

front of your foot (your toes) push downward

against the ground
