>Does your analytical equation analysis take this into account?
well, it's not my analytical equation. :smile:
user JBA suggested that this may be a simplified approach to the problem so i was trying it out.
any ideas?
i've max'd out the elements on my FEA program, and it changed the numbers, but it didn't seem to change them much.
i'm still puzzled if maybe I've made an error in following the suggested formula, or perhaps there are limitation in my FEA program (autodesk fusion 360.)
here are shots showing...
JBA,
so i gave it shot - but i must be doing something dumb. the answer isn't making a lot of sense.
here are a couple of images from my FEA program. I'm using a 12" titanium pipe, and applying force to it in a 10mm radius.
i'm using "safety factor" to determine when a failure occurs (when...
thanks (and thanks to jack action for all his help).
"hurting" means permanently deforming the frame.
i'm trying to figure out if some predetermined impact energy will hurt the frame.
yes, I'm using fusion 360 do to FEA simluation.
so this all seems pretty complicated. estimating t seems like i could easily be off by an order of magnitude.
i found an article that is relevant that i found interesting. it doesn't solve my problem, but it helped me understand some of the issues...
someone suggested something like this - does this sound right to you guys?
The force exerted by the Object on the Rod to bring it to rest is equal to the rate of change of momentum (Newton II):
F = dp/dt
The momentum is:
p = sqrt(2mE)
where E is the energy (assuming non-relativistic...
hi guys - this is not a homework problem. I'm way too old to be in school - I'm actually trying to solve a "real world" problem and I'm just a dumb computer scientist pretending to be a mechanical engineer. I'm working on designing a frame for a vehicle and I'm using a couple of different...
cool. yeah, that's a good idea on the drag coefficient, i guess that makes a big difference. i think i have some ideas on that.
anyway, thanks a bunch! good on you.
i'm not a physics guy, or a mechanical engineer, but i think this should be a really simple formula - I'm assuming some of you folks will know this off the top of your head:
okay, so I'm trying to figure out how big of a winch to buy for a very large tow truck i am building. winches are rated...
Homework Statement
this isn't a homework problem, but i guess it's a basic enough question that i figured i'd post it here.
okay, so I'm trying to figure out how big of a winch to buy for a very large tow truck i am building. winches are rated based on how much they can pull. eg. a...
it's about 11' long. all the relevant data is here: http://utahmvc.org/blankfiremodel.pdf"
removing the springs might be difficult, but replacing or removing the oil would work. of course, the blow back from the recoil might damage the recoil stop as it wasn't designed for a slap back w/o oil.
weakening the recoil mechanism might be something i could look into, but it wouldn't be easy. the recoil mechanism is made of armored steel and weighs several hundred lbs. -- any modification would require major machining and surgery.
i may experiment with draining the oil from it, and...
i'm not quite ready to admit defeat.. :wink: I'm hoping to achieve some recoil - some noticeable fraction of the normal live fire recoil is what I'm going for.
so yes, it seems clear to me that without a modification to the gun mechanism, this won't be possible.
the two possible...
