The work done is equal, of same achievement that itself takes matching effort_X against to overcome.
DdRT just more in powerband due to the 'transmission' gear shift to 2:1;
@co$t of more friction for the redirect arc that SRT doesn't have.
So i kinda would vote for more total effort in DdRT due...
Solar Plexus as Center of Gravity/workload.
Keep it close to rope/lift line, more work the farther CoG drifts from rope.
.
Leg push as a compression inherently tries to move CoG away from rope.
>>Arm pull as a tension inherently tries to move CoG into the rope>>but is less efficient...
i always thought soft, everlasting, non-corrosive adhesive between legs to eye, then hand sewn would be answer.
Where the adhesive kept it in place and the stitchings would just assure the positioning of the adhesive and mated parts w/thread as a 2nd stringer, not main force incurred.
As like...
i picture an Aristotle, Einstein or Hawkins etc. as of brains working so hard;
"head grew heavy and sight go dim"
as lots of actual calories burn hard in thought, possibly heating a room/as like any other machine.
This continues even as eyes close, and things still being sorted, answers found...
Wow, 3 wraps Natural fiber shows as 10x the stopping power for a Round Turn @540degrees on wood vs. nylon on aluminum on chart.
We called the drop/delivery zone as the KZ that no one was to be in.
choked/girthed to carabiner is nice;
but at a loss of 'free ranging' of natural rotation of sling to even wear,
and self adjusting for evenly loaded support legs as changes angle thru rig movement ;
and then also displacing more easily the stiffer 'seam' of the Standing Part from the 90 degree...
i think that at one time there was no mathematics; until drew together the commonalities of what the baker, cashier, builder etc. used in their day to then sift out the common architecture of math we have today. Kinda not the sweat arbo's envision as work to move ball forward; but yet the ball...
@Tom Dunlap sig.
i can understand what you are saying here over the years, and seen some reasons for it.
.
But what do you call it when tracing down knots, mechanix etc. for 20,30,40 yrs relentlessly and sift linked common principles across all, even from different fields for ages of aha's...
i think simple multiplier would be proportional as say;
but, much of this has at least 1 factor that goes beyond with squaring or other exponential expansion.
.
As like i think that in E=MCsquared
Mass is a multiplier expansion of more predictable proportions
but the C is on beyond simple...
Foot ascender thinning rope under hitch can also remove the mushroom swell shelf below hitch from going from loaded to unloaded profile, as sometimes a safety issue.
Captive eyes do present fault of looking like on carabiner correctly when not;
where w/o captive eye would disarm/fall off.
They do allow more self adjusting position to equalize and rotation to even wear;
where tied/sewed on for same approximate captive purpose does not.
This high kick thru...
Might try right hand pull back waist high w/body lean; guarded ready for leg to stop forward movement if impacted.
>>And (s)light upward pull as also grip with left, ready to go with straighter pull w/o upward
>>turn some of the maths upside down with direction reverse of upward, not downward...
Yes,
Very nice savable link, ty/stolen/adding to my deck.
.
The rope as a support column, is sheared across by it's own weight at the Samson angle..
>>It's own weight acts towards leveraged sweat/swig; just no 'purchase'(ABoK) taken/captured from the tensioned side of the system.
.
In a rigid...
Would stand ready to take wraps external to Porty, on trees etc..
Part of reason for some lead between 'tailer man'(capstan) and Porty.
Sometimes start there and back off extra frictions after /during fist hit.
Let the metal take the brunt, be a heatsink and added bark frictions the just trim...
Then 150# climber in SRT can descend as easily as 300# climber in DdRT??
>>as both are 150# at the friction hitch to host lifeline
Tried to show NOT of 125# climber can't descend SRT as easy as 300# (or even 400#climber) DdRT.
Think we should watch the magician's other hand on this.
.
i think...
in my distort(our)ed mind.
The DdRT has 2 legs of support yes, and feeds from a single leg pool to a dual leg support yes.
Half load per leg of DdRT is lesser load per leg vs full load on single leg SRT , yes.
.
BUT,
A 300# man can descend on a DdRT @150# per leg.
>>but a 125# man still has the...
i always look at it like could get pulled into the braking device like they were open farm machinery of gears that will pull you in and chew you up/hands at least. Always visualized such things as greedy, hungry monsters looking for that opportunity, and give that bear a wider path of respect...
