Ergonomics involves proper height and viewing angles of your work space as well as proper lighting and space in your work area. Ergonomics improves work efficiency because employees are more comfortable and feel better in the work environment leading to a healthier body with good ergonomics.

**What is the 'Gilbreth system of motion analysis' (1 paragraph)**
The Gilbreth "system of motion analysis" studies work motion and fatigue and helps to crrect this. Gilbreth discovered in bricklaying there is a lot of unnecessary stooping, reaching and walking causing the work to take longer than necessary to complete. The continued stooping to pick up brick and mortar created unnecessary strain and fatigue on the workers and caused a delay in the work therefore he developed a scaffolding system to correct this problem.

**Who was Frank Therblig, and how did he utilize 'motion study'? (2 paragraphs)**
Frank Gilbreth was a bricklayer, through this work he began looking into motion study as he had analyzed a system of motion analysis through his work. He utilized motion study to make simple tasks more efficient and less straining on the workers. This leads to happy workers and faster work being done. Motion study helped him understand the dynamics of a human body and how it works.

**Describe three categories Frank Gerblith used in the Therblig Analysis Checklist. (3 paragraphs)**
First category "reach and move" checks whether the distance to obtain an object is reasonable or if it could be shortened. This category also considers if there are better ways to access the object either with extra help (i.e. a wheelbarrow) or whether the object could be moved closer to the task. The "grasp" category looks at how many items can be carried at once. This also looks into whether anything can be used to help carrying/grasping the items to move them from one place to another. "Pre-position" is keeping or fixing the spot of an object. Extra tools or devices (such as a clamp) can be used to fixate the object to help make the job easier.
