This video defines The Single Cylinder View of the Human Body
The Single Cylinder View of the Human Body is a theoretical model that replaces the complex human body with a cylinder, located as shown in this picture.
The diameter of the cylinder is approximately as wide as the waist of the human body.
The next picture shows a profile viewof the single cylinder / human body combination.
Then a rear view of the two objects is presented.
Next is an overhead angled view of the front of the two objects.
Then an overhead angled view of the rear of the two objects,
And finally, a directly overhead view of the Single Cylinder View of the Human Body.
One of the major identifying characteristics of a cylinder, is that a cylinder naturally rotates because it is circular. The main idea that is meant to be imparted by The Single Cylinder View of the Human Body, is that the human body can rotate like a cylinder.
As shown in this animation, the entire body can rotate to the right or to the left.
The torso of the human body also has the ability to rotate by itself. In the following animation, the arms the legs are separated from the torso for clarity in demonstrating the torso rotating by itself.
The details about how the torso appears to rotate by itself in real life, will be explained in future videos, about The Single Cylinder View of the Human Body.
A natural question that might arise,
from viewing this picture of the Single Cylinder View of the Human body,
is why does the cylinder enclose,
only the inside of the arm?
Why is the outside of the arm, not included within the cylinder.
The answer to that question will also be provided in future videos about the Single Cylinder View of the Human Body.
