2. Introduction
Anthropometry
“Anthropometry is dealing with the measurements, motions and biomechanical
aspects of the human body and body members, as well as the working posture and the
forces to be exerted upon the objects surrounding the worker.”
In this practical we measures several anthropometric data of our batch and analyze
them.
1. Standing Height
2. Seat Height
3. Seat Depth Breadth
4. Seat Breadth ( hip)
5. Elbow rest height
6. Shoulder-seat height
