Circular to Linear Task

[ktbug]

I am new to this but I was wondering would a pulley would work? The pully is rotating around a fixed point and then lifting somthing in linear motion....

[Uncle Fester]

Pulley? No. String entering thye pulley is linear. String leaving the pulley is linear. No change at all.

But, if you mean a powered wheel hooked up to a motor rotating and pulling a string, yes, that would work.

[Uncle Fester]

that would be okay- circular in, linear out.

Could a marble going down a track and then looping once and then into a straight line count?

While a marble traversing a loop is circular motion, I'm not sure if that circular motion is actually being converted into linear motion. Don't risk it.

Would a fan convert circular to linear motion?
I'm just curious; I already have a good circular-to-linear task implemented, and I already have a fan for the moving air task.

Any ideas on how to reduce rpm without using gear ratios? Rubber bands on wheels is the best (bleh) I've thought of.

Use bigger wheels? Or if you're using a motor, just lower the voltage.

I remember last year I was trying to get a motor winding a string to turn as slow as possible. It was the moving object for 30(?) seconds task. I ended up having the motor's string wrap around a separate, larger wheel. The motor turned the wheel and another string was wrapped around the axle of the wheel at the center, and that string pulled the object. I also had a couple resistors attached to the motor circuit, but you have to be careful not to use too many or you might get a nice and slow motor but it may not run every time.
