Day 13 - Refine End Attachment
By this point you should have a fully constructed base and arm. If not, have half of your group finishing up that part and the other half of your group focusing on today's task: building the attachement that will actually pick up the cups. Although most students use claw designs for this, there are other options (like straps or scoops) that you may wish to consider. Keep in mind that you should have a fully working prototype by Friday of this week. Be strategic in your use of time and materials and do not let any member of your team sit around doing nothing. This is a competition!
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.
