if a vehicle ( model or real size ) had 4 different diameter wheels -
and it was free rolling ( no motor ) downhill --would it track straight ?

same question --but this time there is a motor hooked to ONE of the rear wheels ?

One wheel being driven. Nope!

I don't think so....

I say yes because they do not share the same axle elevation. If it is rolling under the power of gravity only, say downhill, it will drive straight.

Yeah I agree,it should track straight.
Most motorized go carts are one wheel drive so I say YES!

It will spin like a TOP no matter it is down hill.
One wheel got traction and the others are idlers.
The slightest friction from the ground or bearings will make the idlers slow down and the wheel with traction will draw a larger or smaller circular path.

Ira is getting a kick out of this I bet.

Picking our brains.

I'd say its a 50/50 chance it does one or the other

 

[redbenjoe]

the answer is the same --with or without motor -
the trick is to place some weight over the 3 ' idler ' free-wheeling tires -
then it will track straight --up hill / down hill --any way you point it -and no matter what the wheel sizes are ..
should be the same for REAL cars and trucks ;

here is todays updated edition -
drill is on the bottom --where it belongs ..
all 4 wheels are the same diameters ---
soft rubber --plenty of traction -

only $20 for this 18 volt drill from harbor freight - includes battery and charger --

Booya.

most latest mods are the crash bumber -
and the worlds most cheapo up-down ' see-saw ' ramp

That looks like fun

That looks like fun

I'm not sure where, but I know that I have seen somewhere on the forum stated that Ira is Legend
