May the climber's forces be with you

i was trying to explain this again last weekend, and i once again heard how it didn't make sense, was junk science etc.
.
i've been using this strategy in different forms since teenager, thought it was all separate tricks.
But distilled out the common elements; and found link between stiff and rolling levers to use as same.
This allowed me to carry this powerful strategy to more things; and understand others.
.
Simply, you can reverse forces usually pressing down into ground, to pull up on load.
This is counter-intutitve and can fool eye.
.
Simpler to see, just with bodyWeight as ballast to float load, usually bodyWeight expresses downward on ground, not up on load
.
.
If you lift something, it is added to your bodyWeight show above; so now both push into ground
1st class lever reverses these downward forces and makes them pull up with the original effort pull up on load.
Shown is input arm effort or input leg effort for more return
.
.
This can be done with a stiff(board) or flexible(rope) 1st class lever system.
Like an electrical circuit, re-wire force flow to pull up on load, not 'short out' to ground!
Like a 220v fuse box, don't use 110v, when really need both legs of force produced; give it the full 220v!

Application of 1st class lever effort + E/O of effort + bodyWeight instead of just effort!
Then impact forces as can.
.
.
As a has been gymnast; i've exercised orchestrating different force flows,
concentrations thru body frame, this takes some of that, but hi payoff!
i remember ol'coach yelling, that pointing toes and tight body made action easier (longer, more tighter leverage),
but we always thought it maid it harder; cuz had to think and apportion forces thru body frame.
But once you got it, you see what's up/ was a fool to do any other way!!!
.
It has been same for eldest boy; in/out of Akido (hence Will of the Ninja) for years:
be strong, but focus on orchestration,timing and application of mechanics not shear strength.
He is also back in school working on masters in engineering( following in steps of his grandfather and Natural father/died of MS)
and so has been a double check, taken things to professors etc. over the many years of much of the 'crazy math' i post on.
BUT we never found any of this body mechanic, 1st class lever E/O + bodyWeight stuff in engineering books,
as everything taught is architecture outside of body;
but still, the motions are correct; just not written about!
Same for martial arts manuals, not written about;
but if you break down some of the moves; do seem to follow the same prescription!!
.
Above see 3 moments of forces to orchestrate together (tough loads)
or sequentially (lighter so 1 or 2 forces to get moving, then add more after to maintain motion)
Force: Slamming spar on trailer
Force: bodyWeight on spar
Force: effort lift (at same moment E/O of lift expressed
.
Not Shown : leverage 2 axis-es at once't >>
Can also slam down on trailer leveraging long axis of spar;
then as going on allow to slop some so starts loading across trailer width some
and then can spin short axis of spar to leverage that axis too and help walk Cog onto trailer.
Center of Gravity(CoG) forcePoint goes on trailer; carries shape of spar with it!
.
More to trailer loading, and orchestration of body forces to most correct:
.
Back to rope, compounding systems that conserve forces:
an old ship manual with a 3/1 not on end of 5/1 so that 1 end of 3/1 pulls on ground/outside of system
but rather, purposefully chooses to pull BOTH ends of 3/1 from inside the 5/1 pulls
Also note both ends of 3/1 adjustable; high:friction hitch. low:easily adjustable simple hitch

Your stuff is brilliant, I do sometimes struggle to follow however
Thanx, sorry for the struggle, will always answer any questions etc.

Been staring at this a long time, perhaps distorting vision/expression try to decode, there's over a decade of stuff here alone..
Used to think this principle was 10 different tricks;
traced down to root(finally) of equal and opposite thru 1st class lever, reflected back onto work target;
then expanding back out from that distilled pivot found more uses
.
Let's turn this maze upside down and see how path looks!
i was 135# dripping wet, rescued 360#man (that thought he should climb despite his epilepsy) i had 1 pulley ran up tree with...
.
.
i remember that big bear's furry arm darting out trying to grab me like a drowning man; as i went straight to him,
i said oh no, went overhead to lift out rather than calm within reach of scared bear!
.
Years later he asked me what i would have done if didn't have enough lift;
explained would have let him grab lift rope also,
as he couldn't pull down 100# on control side, w/o taking 100# off load side..
(as it was, i used leg lift as effort input, rather than arm effort as input).
.
edit ol'Joe is gone now, disease whittled him way down...
When he was 18, somebody figured to try biggest guy in bar.
Joe did 7yrs for manslaughter, because underage drinking in bar..
hit the guy once; bar 3 blocks from my house...
.
There was no way i was going to let that big monster of a man grab me...
Burnt into my brain is pic of that big bear paw coming at me..

To me all this is rope mechanics, with most correct mechanics available.
Down to the simplest things and why is this more correct than that etc.
'Left-Hand' Sheet Bends and Bowlines are said to be not as secure, i think this is why.
Quite simply, these leave a 'free ranging' Bitter End, that is not seized properly
>>not sandwiched between strongest rope tensions/surfaces by Rope Nip.
