Day 07 - Confirm Measurements
Your drawings should be complete or nearly so. Add measurements, being sure to check your marked-up photo of the test environment to be sure that your design will be able to swivel from left to right far enough to cover at least 3 cups plus the bin, and that the hinges in your arm will be able to extend and retract enough to both reach the closest cup and push out far enough to reach the bin.
If your photo does not have this information, you need to fix that today. In your final EDP report submission, photos are required to have full measurement and angle markings.
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.
