===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

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

Our current Drum: http://www.surpluscenter.com/item.asp?catname=hydraulic&item=9-9003

'''Options for drum brake:'''

Fits our drum, but costs $560 : http://www.jegs.com/i/Currie/272/96226/10002/-1?parentProductId=756792

Does not fit, but demonstrates that there may less costly options: http://www.surpluscenter.com/item.asp?item=28-1324&catname=

There are two commonly used types of brakes. Drum-Brakes, and Disk-Brakes.

This is the motor we have: http://www.surpluscenter.com/item.asp?item=9-10419&catname=hydraulic

This motor would have been better I think: http://www.surpluscenter.com/item.asp?item=9-7703&catname=hydraulic
