3 wheeler

1. steering mechanism

   • rack and pinion
     • simple to make
       • not very secure if not done right
     • simple process
       • minimal parts required
   • gear system
     • simular to rack and pinion
       • more moving parts
         • hard to manufacture
         • gears must be placed perfectly to link up
     • large component
       • will use up alot of space
         • project will have to be larger
       • motor must be included in design
         • wiring+soldering
   • hydraulic
     • difficult to design
       • complex setup
       • uses up alot of space
     • hard to manufacture
       • numrous components
         • difficult to position
           • must be leak proof

2. Rear propulsion

   • gear system
     • must be placed correctly
       • gears must link together
       • alot more components to include
       • hard to install on project
   • pully system
     • simple to design
       • small amount of conponents
         • pullys and belts
       • pully can slip
     • small parts
       • dosent use up much space
     • simular to chain mechanism
       • placement can be adjusted
   • chain and sprocket
     • simple to design
       • can be adjusted to size
     • easy to position
       • chain can slip

3. seat layout

   • one behind the other
     • takes up less space
     • distributes weight
   • side by side
     • front must be wider
     • takes up a larger area

4. aerodynamic features

   • passive (fixed)
     • no mechanisms required
     • not as effective as a active one
     • easier to manufacture
   • active (moving)
     • very effective
       • adjust to speed
     • hard to make
       • moving parts
