Final Fail Safe Designs

Over the weekend we were able to finish making our designs.  After a lot of trial and error, we finally decided to put the upstop wheel on the bogie.  Keeping it stable would allow it to be more reliable.  It would also move away from only being useful as long as the steering mechanism didn't fail.  We've decided to place it in an empty portion of the bogie that already has a hollow square bar in place.  Additionally, we designed the hooks and placed them on our system.

With our designs in place, we are now focusing on stress analysis.  Also, we are waiting for the other sub-teams designs so we can start putting everything together and making any adjustments to the design to make sure it all fits.  Our current worry is that the upstop wheel may be in the way of the steering mechanism.  The suspension system also may get in the way of the hooks or the third bogie.  We have kept all of this in mind, so we know our designs are adjustable, we'll just need to see where everything goes when assembled.

Today we will be meeting with Professor Furman and Ron so they can give us feedback on our new designs.
