Week 26: Revising Ribs?

Work for this past week focused on recycling and repurposing old small stock from test bends to be used for ribs for the solar team. The current design for the ribs includes a tight bend, which can be created manually but greatly stresses the material. There are several potential remedies to mitigate the effects of concentrated stress at the bends, which are causing issues with the ribs at current. The aim is still to complete the ribs by next Wednesday.

Next Wednesday also has the team's first presentation for the semester, as well as a literature assignment due at the same time.

Test bend #1, plywood block buckled.

Solid aluminum block should not buckle.

Test bend #2, tab cracked and broke off from the sharp bend.
