Mark Hawkins - Second Design Revision

This revision of the design had two objectives, firstly was to simplify the joint on the leg design, and secondly to redesign the beam to the stress analyst's specifications.In all images the original design is to the left, and the revised design is to the right.

The ball joint in the leg was replaced with a much simpler structure in order that the manufacturing costs could be reduced. The image below depicts this change.



The next change was the beam. The stress analyst decided that the best beam design was an I beam as depicted below. The dimensions are no longer arbitrary for all designs, but as calculated by the stress analyst.



In order to fit this new beam to the structure, the shoulder and beam pins also required redesigning. The head of the shoulder was reshaped and the pins were lengthened as shown below.





The design is now complete, pending analysis by finance, and full engineering drawings will be posted here shortly.
