    “Rope Only” Canopy Anchor??

    The loaded axis of the Bowline is best end2eye, and for Butterfly as similar utility but end2end. . Many times have used throwline>>pull line into place >>Running Bowline eye on control side, with loaded side, Standing Part 'reeved' thru eye. On far side of eye can tie throwline already in...

    Linear Force as a Dimension Model

    As i know them, these are the UNIVERSAL rules. Linear Force as a Dimension Model; also fully implies the same rules about length or distance expressed, because force and (more visible) distance are reciprocals. . Distance expressed in part or full is displacement against freespace; while force...

    Another physics spinoff question - back leaning

    To me backleaners are different; we pull/push CoG up the hill to over the hinge pivot as highest CoG point, then past, to reverse the pivot from rear of hinge to front suddenly to then splash down on the front side. . Greater range of movement, more favoring a balanced load across w/o side lean...

    Guy rope angle for side lean pull over

    To me, all is geometry of rigid force displacing against other. >>distance displaced against freespace, after displacing against forces matched. Can force hinge stronger in time before commits, by making fold earlier/thicker, as like training stronger like running w/50# backpack, to the release...

    Bend radius for rigging

    Playing it backwierdz, to scale, immediately know/warn more force on cross axis to watch out for, than main target now at that efficiency ratio given is below 70.7%median as a benchmark: If 100# hang takes 150# of tension to be supported >>the 150# tension of POTENTIAL support is only expressed...

    Bend radius for rigging

    Brummel is excellent theory, and maybe close enough; >>just going with model of imperfect exchange, always has to be some even trickle of friction etc. co$t of conversion(or maybe 'Kennedy bullet' would still be flying) . Some of my many lessons of Iron Cross on still rings chase in...

    Bend radius for rigging

    Like a battery to circuit, the wiring of rope and host are unloaded until 'lit' by the initiating force of the load, then trace geometry. Electronics can give changes and commands by circuit, geometry is the mainframe of engineering both mechanics and position. SPart(Standing Part) is the...

    Bend radius for rigging

    Yes, in Big Al's E=M(static mass of resistance against achieving dynamic state of change)xC(dynamic state of change achieved)SQUARED just as in total power in watts=wire resistance(nominal static against achieving dynamic state)x amps(speed of dynamic state achieved)SQUARED. It is the AMPS...

    Bend radius for rigging

    Nice; Caught me by surprise until thought about it: Doubled, double the strength figuratively, drops elastic dampening response. >>does not invade (Max)'headroom' quite as deeply, so less elastic response in return.

    Bend radius for rigging

    i think: The more a given rope organically resists bend, the more bend radius matters against maintained tensile capacity, the more harsher an impact it takes the deformity from pure linear column of force. >>larger diameter host also distributes wear and frictions/heat. Also where linear forces...

    Bend radius for rigging

    All the math to me is 'simply' the same here and everywhere. The aligned directional dimension (cos=100%) >>and it's non(e) of the crossing dimension (cos=0%) as purebred extremes, as knowns that are totally void of each other as each other's non(e). >>only possible values of force etc...

    Throw line/ throw weight thread

    i always thought throwline kit was cheapest tool that can also $ave the most money upfront at start of job... I prefer slipped anchor connection. Without BS I like spread balanced pendulum swing between knees. Pretty good at 'walking the dog' a bit, by snapping hard off lower limb to flip...

    Physics Question: Basal vs Canopy Anchor Forces

    . Not inventor but accepted as lead capstan formula/root work to what i show :The Mechanics of Friction in Rope Rescue by Stephen W. Attaway, Ph.D. for the International Technical Rescue Symposium (ITRS 99) >>full kudos and many thinks for doorways opened. . Very sorry, seem to have somehow lost...

    22 year old died in Florida yesterday.

    . i eventually had to go back and watch before page_3; to weigh for self; and don't do social media. Reading/hearing now about this stuff going online makes it even less likely will find time for social media. Not against it necessarily... . i think Steve speaks more royally/loyally of taking...

    Physics Question: Basal vs Canopy Anchor Forces

    Backwards is always good way to look at things, even if just as a parity check of what regular way looks like; but oft gifts different view too. Just like a tough maze, played backwards as a kid. . There are 2 dimensions of forces here: horiz/vert at play; depends on if and how you may...

    Downed pole with live wires

    i was shown for high power lines down, can lead with bare forearm and watch for hair movement. Not sure how much charge that takes, but seen it work.

    It is truly, truly a wonder, how can pareto/'pare to'(link) the same vital few pivotals, that blossom to so many outcomes that we chase on outer layer >>going instead to other end of the pivotals not outcomes >>can sometimes eliminate chase >>as it is all there>>pivotals with input/output arms...

    backwards walking

    Reverse thinking always good exercise, and sometimes solution or parity check of solution; but many times a fresh look in any case. >>even as tough maze forward when kid>>sometimes more sense backwierdz.

    Physics Question: Basal vs Canopy Anchor Forces

    To me, the over the top lacing usability performs better: >>doesn't just test, but braces the top >>thus can flex top more sometimes with more confidence>>which is more input pull >>would seem to give more of a rolling input to a rolling output, especially to backlean >>easier untie after down...
