156B Week 9
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
All baskets have been weld and have an inner diameter on average of 77.5 cm [30.5"] which is just large enough for the longest components to fit inside
All support poles have been drilled and are ready to be attached to the cross-bars (we tested it and they all fit).
Cross-bars are in the process of having support bars weld onto it to ensure structural integrity
When the whole cart is put together, the cart twists because all the baskets are not attached onto the support poles, they merely slot through the holes.
We are still in the process of analyzing the centrifugal brake, but don't know how to determine what assumption to make for the force that acts on the cart to start the spinning
Accomplishments from Previous Week
Support poles are complete
All baskets have been weld and are ready to use
Heavy duty lazy susan has been delivered and is ready to be placed onto baseplate
Casters are ready to be attached onto baseplate
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish analysis of centrifugal brakes (Kelli)
Prepare dimensions for the stainless steel wire separators and prepare dimensions on the baseplate for the lazy susan bearing (Annie)
Finalize design of the hard brake to stop rotation of the cart (Yuji & Jonathan)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Sponsors requested all documentation that we have been taking on the project: pictures, videos, presentations, reports, etc. (in person, 3/1/19)
Sponsors are excited to see the final physical design of the cart by Friday 3/8/19 (in person, 3/1/19)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Find engineering standards or OSHA standards of the maximum tilting angle our cart can have (in person, 2/28/19)
Dr. Tustaniwskyj said that he would help us find the standards because we have been having issues trying to find it
Do analysis on the weight the bearing can take using bearing clearance distance from specs (in person, 2/28/19)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
N/A
Risks and Areas of Concern
May be difficult to weld the whole cart together
must discuss with Steve how he would need our cart to be set up to prepare for welding
How can we prevent the cart from twisting before the cart is welded
Resources or Information Required but not Available
Once the whole cart is weld together, how fast will it spin in the wash
Schedule
Finish building cart together and hopefully have it all weld by Friday 3/8
Budget (list amount spent and amount remaining)
Spent: 769.45
Remaining: 532.71
Progress on Report and Webpage
2nd draft of report has been finished and peer comments are being reviewed
More information is being continuously updated
Webpage has been updated, still in the process of being finalized after cart has been fully assembled
