Day 06 - Generate Technical Drawing of Prototype
Based on the design you chose yesterday, you should be able to initiate technical drawings today. Each member of your team is required to complete and submit a technical drawing of your planned build. You may choose whether you want to submit an isometric drawing (3D view) or an orthographic drawing (top, front, and right side views). If you do not remember what these are, consult the image below and make use of Google. You were introduced to technical drawing standards in STEM 1 and we spent a full month on the topic in STEM 2. Help each other out as needed, but each student needs to complete their own drawing. If you choose to do the orthographic drawings, you must line them up so that all three views are clearly of the same object.
The most important part of your design will be the end mechanism that picks up the cups. It does not need to be a claw - there are other possibilities if you think creatively - but it does need to be drawn so that I can see what parts move, how they move, and that they are sized appropriately for the challenge.
Hydraulic calculations
- calculate the area of a circle (Acircle = πr2).
- calcuate the mechanical advantage of a system (M.A. = Fout/Fin)
- know that in general, output distance traveled must be multiplied by M.A. of the system to know input distance traveled
- calculate the volume of a cylinder (Vcylinder = πr2h)
- calculate the radius of a circle given its diameter (r = d/2, or d = 2r)
- know that in general, M.A. = Fout/Fin = Aout/Ain = Δhin/Δhout
- hydraulics
- the branch of engineering concerned with the conveyance of liquids through pipes and channels, especially as a source of mechanical force or control.
