Day 04 - Know the Environment

A major part of properly defining a problem in engineering is knowing the specifics of the environment in which your solution must perform. In this case, we have a table configured with mats, clamps, bins, and cups. You need to measure out angles, distances, and weights. All that information must be recorded in your EDP report.

To make that information easier to follow, take photographs of the set-up, import the photos to Google Drive, and edit them in Google Slides to easily add arrows and text boxes. Use the Snipping Tool to take a snapshot of the slide and paste it into your EDP report under the Define the Problem section.

Once you have done this, begin to research existing designs of DIY hydraulic arms. Most are made from cardboard, but you'll see other options as well if you look for them.

Hydraulic calculations

1. calculate the area of a circle (A_circle = πr²).
2. calcuate the mechanical advantage of a system (M.A. = F_out/F_in)
3. know that in general, output distance traveled must be multiplied by M.A. of the system to know input distance traveled
4. calculate the volume of a cylinder (V_cylinder = πr²h)
5. calculate the radius of a circle given its diameter (r = d/2, or d = 2r)
6. know that in general, M.A. = F_out/F_in = A_out/A_in = Δh_in/Δh_out

hydraulics

the branch of engineering concerned with the conveyance of liquids through pipes and channels, especially as a source of mechanical force or control.
