Anthropometric Data and Analysis

32nd batch

Ergonomics Assignment

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 Height2. Seat Height3. Seat Depth Breadth4. Seat Breadth ( hip)5. Elbow rest height6. Shoulder-seat height
