Water from others

This picture from 2008 shows how much we had improved the design of our water fenders. The water is flying backwards!!! This really worked well at competition and got us a 11th place in Water Manuveribility.
For the 2008 year one our big focuses was on the water section. It was an area that we really struggled on in 2007. We came up with a pretty good system for 2008. Our goal was to have the wheels rest a little less than halfway and have ALL of the water from the wheels get directed back. To do this we first changed our tires from stud ilke ones, for a light mud tire. These tires had a chevron like pattern which enabled us to really move water. The next thing we did was attach a metal plate to the edge of our fenders that had slots in it where th bolts attached. This allowed the metal catch plate to be adjusted so that it was almost touching the wheel. By using this adjustable design we were able to catch almost all of the water!

7th Full(ish) Meeting Minutes

For September 24, 2009:

Project Requirement Paper due has been pushed backed to October 1.
- It should be one page, listed how he described before, and with a short opening and closing paragraph.

Looked for gear, keeping in mind of the 44:1 ratio.

Looked for more specification for the water trials but found little.

Preliminary duties/assignments were set for each group member.

Preliminary frame design 33% complete.

Manuel will write a first draft for this assignment SEP 24 TH: PROJ. REQUIREMENTS DUE

Registration for the competition is October 5 and must be made quickly as space fills up fast.

4th Full Meeting Minutes

Brainstorm leads to final choices.

- Aquatic- Not chosen until rules come in.
- Drive Train- CVT+Reduction Box, maybe Manual Overdrive - Rear Wheel Drive
- Suspension- SLA (Short-Long arm)
- Brakes- Disk brakes
- Steering- 4 Wheel Steering
- Frame- Strength calculations - Roi is making one a preliminary design.
- Electronics- Listed.
- Ergonomics- Design later

Saving Solidworks File

 UPDATE: You can save it as a Parasolid (.x_t)  it seems to also help especially if you have to run Simulations or COMOSworks.



1. Save as an eDrawing (.eprt or .easm) while allowing full measuring options at the time of the save.

This will allow anyone needing just the measurements to view it in eDrawing viewer free from SolidWorks. 

 

Saving it with the above options allows anyone to measure.

2. Or you can save it as an IGES (.igs) file this way it can be opened and redrawn by an older version of Solidworks.

3rd Full(ish) Meeting Minutes

Sharing Excel Files

Steps for sharing a Google Spreadsheet with specific individuals

1. Login to Google Spreadsheets with your Google account.
2. Create or upload the spreadsheet you wish to share.
3. Click on the “Show sharing options” link in the top right corner of the screen.
4. Add the email addresses of the people you want to invite to either view or edit your spreadsheet.
5. Click on the “invite people” button to bring up the Invitation screen. This screen contains an email message to the invitees. The message includes a link to the spreadsheet and an area for you to include a personal message.

Note: If you send invitations to non-gmail addresses (Google’s own email service) those individuals will have to create a Google account using that email address before they can view the spreadsheet. Even if they have their own Google account, they will not be able to use it to log in and view the spreadsheet. They must use the email addressed specified in the invitation.
