Motor On Tower Temporarily Isn't Turning

[mvas]

@mvas

Depends on two things: the length the axle will span and the load on the flywheel. If the axle spans length is more the full length of the ball (6"+), then use a high strength axle. If your flywheel requires a high amount of compression to transfer energy, use a high strength axle.

I am confused why everyone was so quick to dismiss the idea. For reference, most (if not all) of the 169 teams in TP used HS axles on their world robots. Any minute improvement to the robot is worth it, and a HS axle is simply more durable than a LS one.

Here’s a bit of explanation on my thoughts on an axle. This whole thread in general discusses it.

This is also a noteable reply:

@Aditya_Narayanan

This makes intuitive sense, and would seem to explain why low strength axles tend to bend when used over very long distances, but thinking about it in terms of pressure is not exactly the best way to go about explaining it, because the pressure on the ball need not be the same as the pressure on the axle.

I do want to hear what @marinmersenne has to say

@Athan

If so, how could I avoid this problem?

Screw joints

@333A

The most important takeaway from our research was that you should use screw joints whenever possible. This change had the greatest impact on the stability of our lift, and forever changed the way we build anything.

This whole thread has good coverage on that

BTW

An axle must be connected to the motor in order to power anything. Everything else could theoretically be replaced with a screw joint.
