Day 14 - Adjust Pivot Range
Your hydraulic arm should be fully functional by the end of the bell tomorrow. Today you should test the reach of your arm to make sure it can pivot left and right the full range of the cups and that it can grab the closest cup as well as stretch far enough to reach the drop-off bin. Most of you will need to make adjustments to ensure this works - that is the consequence of not planning out your measurements in your original design. I saw that few of you took me seriously when I explained the need to do this; now it will create additional work for you as you undo some of the things you should have planned around in the first place.
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.
