Thank you all

Thank you, let me read this a bunch of times before I understand it a bit better, I'll never fully understand it but its helpful. I'm guessing Kt here would be the spring constant of the tire? for this I would assume something about 1200 lbs/inch. The other variable that comes to mind is...

Exactly, I said that in my initial post, what I meant by this is how a traction control system works is that I'm looking to use it as regaining traction during loss of traction by giving it a few milliseconds of extra load. Most race teams couldn't use this because it's considered an active...

I agree, is this different than the 2nd link I posted where the return velocity was less than the initial velocity or are you talking about something else? I also picture the wheel moving back up after the impulse but with far less force but you’re saying the force would be exactly the same...

Edit to add: yes accelerating the mass up as I stated the chassis would move up but by how much? Is the rebound velocity and force the same? The reason I posted the other link about return velocity. If rebound force is less then would we have a net gain of load downwards?That’s really the tough...

Which is exactly what any other traction control system does. A lot of variables involved but more looking for where the reaction forces would end up, if the hammer is mounted to the chassis, would it put an equivalent force on the chassis, and would the recoil force be the same as the impact...

Hello all, I wanted to know what would happen if I put a jack hammer system on the unsprung part of the suspension, I posted this on the engineering forum but couldn't get a complete answer. https://www.eng-tips.com/viewthread.cfm?qid=512117 Basically the argument was if the reaction would...

Thank you, that’s the next step. Putting mesh and shielding. If the mods don’t like it then I have no issue with them deleting it. Forum is pretty dead except for Balun helping out.

thank you, I’m having a hard time visualizing this, any sketches of this setup online that you can link? All very interesting, thanks.

I get the thing about the safety and pushing this thing too fast, it needs to be checked for any blade damage or bending and also put some safety mesh. thank you.

Stepping back for a second, I’m hoping someone can school me this, I understand for a lift and drag experiment the flow should be smooth and consistent however my setup is a downforce and drag experiment of a car wing or other car wing parts, I’m not trying to check airflow or vacuum under a...

Thank you, I have no idea what the pdf says I meant the setup they had in it That looks like a pusher fan so I’m going with a similar setup so we need to straighten out this airflow, I don’t think I can go with a puller setup. I have seen other setups with similar setups but I understand the...

balan, thank you Someone posted this, https://www.frh.utn.edu.ar/media/empresa/laboratorios/03_LA_fluidosytunel.pdf is this what you have in mind? This looks similar to what I had in mind. So in order Fan, contraction, honeycomb, test chamber and then diffuser.

Thank you, by closed do you mean closed loop or build the contraction, chamber and diffuser? Of course I plan to do this but do I need to have a closed loop? As for instrumentation, I’ll take a look at the manometer.

Thank you It’s pretty turbulent coming out of the fan, I don’t think I have the space to close it. What are you thinking for measurements? I saw a few videos where people put the wing on vertical sliders, I was thinking of doing that but have calibrated springs to measure sure the distance...
