Ways to Spin a Flywheel using linear motion

AI Thread Summary
To increase the speed of a spinning flywheel using linear motion, a mechanical device can be employed to automate the repetitive action of pushing on the wheel's edge. Suggestions include using a con-rod and crank system to convert linear motion into rotary motion, which is more efficient than direct linear contact. While a hand drill was mentioned as a rotary option, the focus remains on linear methods. The discussion also highlights the potential of using simple devices like a stick or a pressurized water hose to demonstrate the concept. Overall, innovative ideas are encouraged to achieve the desired mechanical solution.

I am to try to find simple way to spin a spinning flywheel. What linear motion device acting on the outside edge of a spinning flywheel can be used to increase the speed of the flywheel. Need to use a repeating pattern such as pushing your hand down over and over on the edge of the wheel to speed it up. instead of using hand want to use a mechanical device to do it automatically. Any ideas would be helpful.

Hello Gerald, :welcome:

ANy other boundary conditions? Are you allowed to use a hand drill ? Bow driven axle ? Foot power treadle ?
 
This is very old, but that stick's linear motion spins the hoop. It could spin a flywheel too. Motion of the stick could be done by machine.

Much simpler is @BvU 's suggestion to use a hand drill, but that is rotary, not linear.

Using linear motion, there is a practical limit to the contact time - at least a rotating wheel against the periphery is the most common way of doing what you want in demonstrations I have seen.
 
Why must it be linear?

Edit: Use something like a con-rod and crank to turn what ever linear source you have to the rotary motion required by the gyro/flywheel.

A crank would be a good way for a human operator but a rotary system would probably be better for most other power sources.
 
I used a pressurized water hose to spin a wheel once when I was a kid to study the friction of the bearings on the wheel

But, unlike many one-off posts, his post managed to spark off some good, interesting ideas.
Must have been a homework topic and he may be getting credit for all these contributions. Ah well.
Was it Picasso who said "Genius steals"?
