Lab+5

**Lab 5** Ergonomics can be defined as the science of equipment design especially for the workplace which enables maximum productivity and reducing the chances of injuries, fatigue and discomfort. (Dictionary.com) Ergonomics can include the design, manufacture and arrangement of products that are safe, healthy and comfortable (Dictionary.com). This can be used in designing office furniture and other equipment. As shown in Humanscale Ergonomics, chairs, lighting, the position of computer monitor and keyboards play a part in productivity and comfort. Ergonomics helps to customize a work area to make it comfortable and accessible for the worker. Gilbreth system of motion analysis studies the relationship between how workers move and their productivity while performing a designated task. They Gilbreth system came about after studying the movements of bricklayers. Gilbreth studied how to eliminate waist motion which would allow bricklaying to be more efficient.  Who was Frank Therblig, and how did he utilize 'motion study'? (2 paragraphs) Frank Gilbreth who stepped in as an apprentice bricklayer wondered why he was shown seven methods to lay bricks. He conducted a motion and fatigue study in relation to brick study which involved unnecessary walking and stooping and sometimes resulted in bricks being damaged. He designed a non stooping platform that improved bricklaying and maintained the level of mortarying and bricklaying at a certain height. This increased productivity and eliminated the stooping factor. More bricks were being layed in a least tiring position thanks to Gilbreth’s motion study. Rest to overcome fatigue focuses on the environment the worker is in. Are temperature, humidity, ventilation, noise, light, and other working conditions satisfactory?
 * What is the 'Gilbreth system of motion analysis' (1 paragraph) **
 * Describe three categorizes Frank Gilbreth used in the Therblig Analysis Checklist **
 * Reach and Move focuses on devices that can be used to eliminate the use of certain body parts. It asks questions such as can distances be shortened to advantage? Can abrupt changes in direction be eliminated? **
 * Pre Position focuses on the workstation itself. **Can tools be suspended? Can a guide be used?
