Sketchy Physics Test

  • Preformed a test in sketchyphysics attempting to simulate a cylinder with a pivot at one end where the piston could slide. The test seemed to show that sketchyphysics could not be used that way.

  • Created a set of build instructions for the "Material Awareness exercise"
  • Built the "Material Awareness structure"
    • Observations:
      • Material is much bigger and heavier than you would think from the sketchup model
      • Assembly works best if nothing is tightened down until entire structure is assembled
  • Disassembled structure
  • Did inventory of 1" bolts and nuts.
  • Did inventory of hydraulic hoses

Information on Overcenter Valves:

Interactive video on how hydraulic brake valves work

We need either a drum brake system or a hydraulic brake valve.

Our current Drum:

Options for drum brake:

Fits our drum, but costs $560 :

Does not fit, but demonstrates that there may less costly options:

Options for hydraulic brake valve:

Still need to determine price and circuit : - See Overcenter valves with brake control

Brake Research Discusses several brake systems, their advantages and disadvantages, as well as how to trouble shoot them.</br> There are two commonly used types of brakes. Drum-Brakes, and Disk-Brakes.

This is the motor we have:

This motor would have been better I think:
