Take a picture of frame or machine. You must physically see it--no internet pictures. Explain why it should be categorized as a frame or a machine. Justify your case using the definitions of frames and machines as it applies to this statics class.
Please write at least 200 words. You will be graded for your effort and insight.
The picture is of a fan. This is a Machine. A frame would be used to support loads. It could also be called a truss. Example of a Frame is a window-frame or a pillars in a building. A Machine may also support loads(like carrying a passenger in a car) but key difference is: a machine takes some input energy in any form and performs some work. Here the work done by the fan is to circulate air molecules against viscocity of the air. Such a task cannot be performed by a Frame as it does not have any moving parts. A machine that is in not operation is performing as a Frame. A dead body is a frame. But a live human is a machine!
