**Write three paragraphs to define the term 'ergonomics'. (3 paragraphs)**
Ergonomics is the science designing of the fit between human and the equipments they use. Proper ergonomic design is essential, because it can prevent you from injuries. For example, the office chairs, it should have an ergonomic design,which fits human's back and also allow them to have the proper height to look at the computer. That way people do not get sore muscles or ache from sitting long hours. It's a way of supporting and protecting our backs.

Ergonomics is very important in life. Without a proper position, it could lead our health into a risk. Everything we use all involves with ergonomics. For example, people spend long hours on computer without sitting in a proper position, and lead to the most common health issue of sore back or muscle ache. Therefore, right position and fitting is necessary.

Ergonomics is referring to the physical objects such as chair, keyboard, monitor, desk and lighting in a workplace. Not every one is the same height or same physic or even have the same risk factors. Therefore, ergonomic goal is to design tools and equipment such as chairs, lamps, computer monitor to be adjustable to meet the individual’s needs and fit better and comfortable.

Gilbreth system of motion analysis is a system of process and movement of each worker while working a task. Through the motion study, Gilbreth can identify the smallest motions that caused delay and then he can use this system to eliminate the unnecessary times and wastes less energy.
 * What is the 'Gilbreth system of motion analysis' (1 paragraph)**

Frank Gilbreth was a engineer who through bricklaying came up with motion analysis. He developed many of the concepts and applications that are now part of modern management techniques. Frank wanted them to be safe at work and more productive with less wasted effort. For the purposes of not wasting energy and improving manual productivity, Gilbreth created “non-stooping scafolding platform and a one motion grasp packet”. This device allowed cutting the human movement by more than two thirds and increased more than double the productivity.
