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.

Then Found the following video...

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

Search "Brake valves to control hydraulic motors with over-running loads"

http://hydraulicspneumatics.com/other-technologies/book-2-chapter-12-fluid-motor-circuits

Information on Overcenter Valves:

http://www.designworldonline.com/overcenter-valves-are-key-to-hydraulic-control/#_

Interactive video on how hydraulic brake valves work

http://www.wisc-online.com/objects/ViewObject.aspx?ID=HYP3707

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=

Options for hydraulic brake valve:

Still need to determine price and circuit : http://www.hydrotech-bg.com/common/d_images/src/file/PDF/E4-ACCESSORIES.pdf - See Overcenter valves with brake control

Brake Research Discusses several brake systems, their advantages and disadvantages, as well as how to trouble shoot them.
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
