Day 17 - Refine Your Design
Again, documentation is vital here: if you don't document it, I have no way of giving you credit for your redesign efforts. We're falling behind on our builds; I have not seen any working end attachments (claws) yet. Make that happen today! As a reminder, during our next class we're going to review hydraulic calculations and how to solve these problems, on the class after that you will get to pit your arms against each other to see which designs are the best and you will turn in your EDP write-up.
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.
