Noseweight advice

Don't know about anyone else ..... I was bored of the pedantry a good few pages back.
I've yet to measure the nose weight of my current caravan ..... I'm sure there's enough tolerance in max weights quoted & it's all level when towing ☺

So how does nose weight decrease when nose up and increase when nose down. It's a clockwise moment whether (or is that weather) above or below the horizontal? Over to you.
Clockwise or anti clockwise? Depends where you stand. No need for complicated proofs. Cut out the shape of a cravan, pin through axle position to a board. Mark out a notional C of G. Anywhere just forwards of the axle. With the caravan cut out looking 'level' horizontally. Raise the cut out by the drawbar. You will observe that the marked C of G mover towards the rear of the caravan. The higher the C of G marked the more evident.

hey I knew the answer! I was testing Lutz.
But moving the CoM alone doesn't do it lengthens /shortens the horizontal distances taken around the moment.
I have to say class that ET and oscid answered the question very well, (what houses are you in for your house points) while one person just said 'what he said'

I have a feeling that Cornersteady is simply trying to prove my reasoning wrong rather than offering his own explanations for observations that were actually made (that the noseweight, or mass at the coupling point as the regulations call it, measurably reduces as you raise the front end of a trailer, for example). I will therefore refrain from further comment in this thread.

We are a bit like you. We tow a Lunar Delta RI (the lowest ex-works noseweight layout in the Delta range) with an Audi Q3 that has an 80kg nose weight max. We've gone to great lengths, perhaps even to the point of being a bit anal on making sure the noseweight is right, even to the extent that the single mover went behind the rear axle not in front. It can be done and hopefully the original poster can get it sorted. I do think though that VAG have shot themselves in the foot with the nose weights on the Kodiaq. Some aren't even allowed to tow, whilst the rest of the range seems to have noseweights of 80 or 100kgs (the latter what I see as the minimum for a largish SUV.

I think you will see that I said it did reduce/increase and said your reasoning was correct but that we view things in different ways.
But a quote from Hamlet, Act III, Scene II does spring to mind

Cheers both for an interesting debate
I suppose I'm lucky in not having the OP's problem, I have a car that is heavy, with good noseweight capability as well as a caravan that is not inherently nose heavy so do not have to work it out to the nth degree.
Therefore, 'that'll do' will suit me fine and am happy to accept the Engineers way of thinking and expressing. But instead of 'here or overthere' I decided to go interplanetary I would bias myself to the mathematician

listen, I'm sorry if in my zeal (and Mrs C could really tell you more about this) for being pedantic or 'purity' I've given offense and yes I have probably made a idiot of myself in doing so.

you must be a very experienced tower as I take it from www.towcar/onfo the percentage match is well over 90%. but I am guessing what model of Q3 you have.

, as to whether I will remember is another matter
