156A Week 10

What has been done in the past week

• Bought materials for prototype. This prototype will be used for next week risk reduction presentation

• Design completed for the Spar and base

• Derive the flow and wave equation (underwater motion)

• Risk Reduction Presentation for professor T.

Feedback from meeting with sponsor

• Await on email for the water temp data and wave/current data from sponsor to create a simulation

• Design feedback. Sponsor liked the updated design. A couple changes need to be made, but nothing too big.

Feedback from last meeting with instructor

• Look into the different PVC/plastic pipes

• Instructor hinted to find better cost effective companies for PVC pipes and plumbing material. In doing so, teammates went to Homedepot and found proper materials. Due to COVID, it was hard to find plumbing supply stores that's open. Therefore, in the next couple of weeks, the team will find better suppliers in the area once stores begin to open up.

List your current concern according to the importance

• Risk reduction presentation

• Assure that the FEA analysis is correct and FEA analysis makes sense.

• Analyze how well Spar and connectors hold the different section together

• Analyze how each components are able to connect joints and respond to force

• Find proper equations in relation to our design (flow and wave)

What is the next step of your project

Tasks:

• Meet with professor Pawlak(sponsor) December 7th 2020 at 1 PM for weekly meeting.

• Assemble prototype for next week risk reduction presentation - Eliran/Ayesha/Erik

• Begin working on risk reduction presentation.

  • Erik - introduction and background information

  • Horim - Governing equations and analysis

  • Ayesha - Conclusion, Gantt chart, Milestones

  • Eliran - FEAs on each component and analysis

• Create website - Eliran Lenard

• Analyze dynamics and decide on use of guy wires or truss for mooring- Erik

• Create zoom link for tomorrow’s meeting with professor Pawlak - Eliran Lenard

• Get lab needs form signed by Ian - Ayesha Riaz

• Analyze the SolidWorks components and the assembly - Ayesha Riaz
