maybe your gay mexican cat resembles a thin spherical shell, but mine is more like a parallel plate capacitor of infinite length

wow these people really don't know the first fuck about physics. really, it's simple logic. study the world around you! read a book or chuck it across the room, either way you're doing physics. physics is the foundation of all sciences. physics can solve all problems. (if it can't be solved by physics, chances are it's not a real problem!).

i can't keep up with your mood swings (pregnancy) but just in case i thought your first post was a joke, since you asked the coefficient of friction on the floor and the coefficient of friction is u. i thought it was good but i wanted to curb the discussion back to my dillema

also the picture of the cat turning helped since objects rotate around their centre of mass right?

Anybody else for euthanasia?

EDIT:
No, anyway if I have to choose, I'd say try it and see the results. Easy.

Ahahahahahaha. This is classic.
Gaming World - We have topics about cat physics. 

Like, I know this is a serious topic, but that doesn't make it any less hilarious.

At least we got something to talk about.

this is fairly appropriate right now

Another suggestion would be to put wheels on the lost leg part I've seen it done. However that sidables him of his ither skill..


On a more serious note, I believe the center of gravity is moving when it walks? So I think would only perfect the balance when he's actually standing, it might hurt his other actions more.

I wouldn't reccomend taking engineering advice from physicists over the internet.

This cat is most likely a personal thing to you, therefore you should look around your family or local community to consult an engineer you can really trust for all of your cat-mechanical needs. Contact your local Veternarian aswell (better yet if you have a Veternary Technician as he specializes in technology), so you can arrange a meeting between the three of you, if you are to come up with the most effective design for your cat-balancing needs.

this is fairly appropriate right now

Now, it's appropriate.

EDIT (For Topic-sake):

If you attempt to change the cat's abilities now, after it's learned to use 3 legs, you'll only further hamper his development and reflexes.

enough weight to counter balance a third of it's body is like three $2 coins. and yeah it's leaning against my hand, i don't see your differentiation, though iirc her stub moves

if it's helped by leaning on your hand, putting a weight no it would only make it worse... it needs to lean on something, not be pulled further down... 

..that means mechanical would be the best bet.

This works perfectly for planets so cats shouldn't be that different. If you put a weight on you cat, it will probably land on the side and break its
neck if thrown out of a window. The dilemma here is thus = make the cat walk in a normal fashion BUT not be able to throw it up in the air or just
give up and let it ADAPT to its disability.

I think a peg-would do though. Not only can you say your cat is a pirate (if you poke out one of the eyes as well), but you could also use it
as fuel for a fireplace if you need it once hell breaks loose on earth and the ice age takes over.

your post quality is really consistent bonehead.

an artificial leg would be the dumbest idea, it'd get caught on everything and it'd be a lot harder to implement

if it's helped by leaning on your hand, putting a weight no it would only make it worse... it needs to lean on something, not be pulled further down... 

on the OTHER side. do you know how balance works?

Touché.

Though bear in mind that there is no such thing as a PERFECT THING so you just have to pick what you feel is best for your situation.
A peg-leg would be easy to implement if you are strong (just grind a stick into your cats body) or if you used ducktape.

If you put ducktape on a fourlegged cat's back, it starts walking funny. Try doing that with yours and please record it because I don't think
that this has ever been documented before.

>>eat cat

an artificial leg would be the dumbest idea

but... strapping a twoonie-

i think your dealing with a more serious issue abotu the centre of gravity here.

without a 4th leg, the centre of gravity will actually change the cat's trajectory considerably.

center of gravity has nothing to do with it. It's because the fourth leg isn't there at all to support the cat's weight on that side of it's body when it moves its rear leg.

the weight would be best on the outside of the remaining rear leg, and slightly behind it.

but honestly this isn't the best idea to help out the cat. You could offset the extra load in terms of balance, but you would be adding extra dead weight to the cat, which would fuck it up even more because it has to support this extra weight with three legs instead of four. Unless you find some way to shift the existing weight of the cat, you won't help it at all. A cheese grater and saran wrap might come in handy in this application.

basically what we can assume is that the cat's center of mass doesn't include the four legs, because no leg is supporting the weight of another leg. The center of mass therefore is the same now as it was before she lost a leg.

the center of mass exerts a moment upon each leg. If we can assume a general shape like so:


and that the cat is made of a homogeneous material, the center of mass on the coronal plane (the plane on which the diagram is laid out) should be exactly in the center. The reaction forces of the legs (assumed to be of uniform length and girth) would then be exactly the same. The mass of the cat, times the acceleration due to gravity, times the radial distance from a leg, divided by the number of legs gives the moment on each leg (the calculation is somewhat simplified here because we're assuming an even distribution of weight, legs arranged in a perfect rectangle, and a CoM being in the exact center of the cat). Since the cat as a whole is not rotating, the sum of all the moments acting on one leg is zero. I won't go through the actual calculation since this is on two axes and I don't have paper and shit close by.

when one leg is missing, the reaction force previously exerted by that leg is not present anymore, so the other legs must compensate. Recall that moment force is the mass*gravity*distance. The front legs experience a small increase in load, but the rear leg must compensate for a much larger load than before, due partly to acting as a lone reaction moment for the front legs, and partly because the the missing leg no longer balances a moment.

Since the cat is not moving up or down when standing, the net vertical force must equal zero. The weight of the cat represents a downward force acting on the body, and each leg represents a reaction force pushing against the body. Any weight added must be borne by the legs.

The statics is perfectly clear in my head but without pen and paper it's hard to describe in just words and I never thought I'd end a post with this, but yeah, don't strap weights to the cat. If it was possible to rearrange the weight that was already there, it would be the best thing, aside from adding some apparatus to it to help bear the weight.
