Day 02 - Worksheet B
Yesterday, the most common problem was failing to do algebra properly. That's why I require you to isolate your variable before putting numbers into the calculator. Show all of your work!
Today you are going to work through Worksheet B, which has the same fundamental problems as you saw yesterday in Worksheet A, but with additional steps required to line up all your variables. These are the pieces of review content you will need to recall:
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.
