Building the Vehicle Physicists Called Impossible (feat. Veritasium), OverUnity?

tinman,

My turntable is 4ft diameter and you went with 23.62 inches.....lol

I believe I have all the parts, so it should be a fast build.

The turntable design will add resistance as will different bearing choices.
I would think you would be better to use a remote control car. Record the speed at full throttle or any particular throttle percentage. Then add fan blades and record the speed again at the same throttle percentage. Or record time taken to kill the battery without fan and again with fan.You wouldn't be adding any resistance other then the fan blades. 
The turntable design will add resistance from the added bearing or what ever used for the center attachment used for keeping it on the table plus there will be resistance from the centrifugal force.

When are you guys going to catch up with the rest of the world, and go metric 

Ok, so my table is close to 2 foot in diameter, as i had no 4 foot wide sheet timber to make one that big.

Here is my setup design video.

Hi Brad,

I will have my update today, my turntable setup with 3/4 plywood I have.

I want to thank you for taking on this challenge, it tells me there is hope in this world of people like yourself trying to build something instead of people who just talk BS.

This would be fun and no matter what happens maybe other can join in with other challenges to build stuff on this forum. It really got lazy with lots of chatter today.

My challenge is not personal, it's seemed like the only way to get people involved today.

Tom.

Mine is coming along just nicely.
Will have it altogether by tomorrow lunch time-if i don't sleep in to late lol.

Got the center bearing swivel all printed up, the swinging motor mount all printed up, the disk cut out, and mounted to a bearing head, and the outer running board is ready to fit once the motor is set up.
