Ever conducted a little (possibly flawed) physics/science experiment for fun, because you're bored or for your own sanity? Then post it here.
Two of mine in recent times are:
- grease slippery-ness test where I greased up the bottom of a weight on a flat surface attached to string that was hanging off the end of a table. I then added weight to the end hanging off the table and recorded which grease required less weight to slide.
-and this arvo I tested out the seal friction on the internal floating pistons I designed around different seal types (o-rings and u-cup seals) for my dual air chamber setup in my fork. This time I took photos of this super serious physics journey.
I clamped a deflecting beam torque wrench by the head in a vice and then tested each IFP at 25psi by pushing on the handle of the torque wrench.
The two different seal types on the IFP's and the dynamic air chamber
And the all-important peer reviewed results of this highly anticipated study
I think I might need to machine a tad more off the OD of the u-cup seal grooves as I think the seal compression could be reduced a little and still allow the u-cups to hold pressure because theoretically u-cups should net less friction.
Fire away with the questions/criticism or experiments of your own (mtb related or not)!
