    Negative rigging

    Sorry for the delay i believe amount of energy induced into support as receiver; would 'simply' be = mass x velocity SQUARED*. . By different version i mean the 2 part break from static resistance to dynamic state change of the sitting force waiting to be overcome, then how much dynamic...

    The Fundamentals of General Tree Work: 25th Anniversary Edition

    Here is thee still 7foot in diameter at 150ft up poster that Gerald Beranek did (he is the one with the brown cast on right foot from crane outrigger set down on it weeks before). Good thing it slowed him down long enough for the camera to catch! He is using a classic Stihl 090 , with chains...

    Negative rigging

    The less headroom/ the more the rope tensile is used, gives greater elastic response returned. . This is so true, that if make a 2x1/pulley on load, where the system has more capacity, and less loaded per support leg yields LESS elastic dampening response thru the system to deal with the dynamic...

    Negative rigging

    In my home-made self taught terms gritty treeman view: . Force needs equal and opposite to express against, or is just falling/displacing distance as Dan said, otherwise is displacing against space not force. Displacement is key term to use, think of like from engine world, more displacement...

    Uprooting Hickory

    Kinda looks more like root ball than root sprawl; even tho still could sit up HARD if a bunch of weight cut off = 'leaf spring' !

    gratitude for applied techniques today

    Understanding a principle to how it works at differing leveraged angles(horizontal rigging vs. felling) X load leverage as it changes thru the motion; can give more definition to the individual parts and processes as a consistent single consistent fabric, rather than just a few individual...

    gratitude for applied techniques today

    YW. Understanding the forces that may be produced by the mechanical commands given is very powerful, then why not to invoke. A Dutchman at full tree scale in felling can 'over rule the constitution of the tree as a container' with the shear volume of force produced and set into a bind against...

    gratitude for applied techniques today

    For felling usage. i do identify any early close used to rebound off of as a Dutch treat, to include kerf closes in top hopping over a fence etc. and undercut kerf then cut down to for snap off of smaller branch pieces as a close for support as cut thru hopefully unstretched fibers at top of...

    Neruo Divergence (ND). In arboriculture

    Wow, Krishnamurti - "Think on These Things". Alone in the air, goggles and earplugs doing my thang smoothly, eyes just inspectors of the fingers aftermath, much time for these thoughts in some kind of pure zone. . in the various studies of movement science and awareness we can see not just a...

    Uprooting Hickory

    If ground not spongy(does not look raised in pic) tension side especially, might fall as some side lean scenario w/o rear rope too, all depends. Side fall would not feed into the fiercest falling force like would happen on falls inline to lean axis as loaded power axis, or even degrees to the...

    Neruo Divergence (ND). In arboriculture

    Well, then too, only a narrow band of that prototype survives let alone thrives in the raw Neanderthalic environment of rawest risks, loads, other forces , tricks and traps!

    Neruo Divergence (ND). In arboriculture

    Inductive Reasoning is inverse of most peoples thought process, if one…. . Being able to work backwards, also lends towards more to hitting target on the run forwards in realtime. As Evo says able to do both ways better, I think able to flip spin in head as hit from any angle more 'owns' it...

    Clove Hitch

    Clove to me is a continuous direction like Round Turn, both in contrast to the counter-torque reverse of Backhand base in Cow. . So we expect some walk in Clove, to probably tighten, but that can go too far seems. We see this even in kinda 'Double Clove' of a Taut Line; we backup the hitch and...

    Rigging Setup Design Factor Poll

    10:1 rope, but this is a trade-off with the amount of elastic dampening response returned. So, 20:1 tensile impacted, can ruin day that a 10:1 wouldn't, by shocking support etc. >>Doubling rope to 2:1 support thru pulley has same effect of increasing Load capacity @ co$t of elastic dampening...

    Bowline slippage

    From ABoK Lesson# 478 "There is unsuspected virtue in a few turns of line." -In the The Tree Surgeon section Lesson#1732 "There's a lot of virtue in a round turn." -ABoK shows in quotes like from another Lesson#1669. "Round Turn on the Standing Part adds materially to the strength of the knot."...

    Quick Block attachment knot

    To me fair build for a 1D pull away from host, But I always like Round Turn base on host for a more availability 2D support structure against a 2D pull. Not trying to lessen that in efforts here, but in my own mechanical logic, this is what I see, and where would point .... . 2D to me pull...

    Studying compound pulley systems, Chinese Windlass/differentials and the 2/1 over own self in DdRT dumbwaiter are key to my understandings and testing of self to same, as chase the rules thru counter intuitive turns and they stay so consistently the same.....

    Favorite Applied Physics Resource?

    This has been a journey for me, and i had lost fm5-125 hard copy long ago, and caught Tom posting same with Sailing Smacks link, perhaps 20+yrs ago and they have been pivotal to unraveling what i have, ty. . But, they were not just magic manuals of immediate knowledge, but rather work, sifting...

    Will a larger rigging ring always make more friction?

    The collective arc frictions that are compounded; are counted in 180increments, but this pivotal work shows can be cumulative sum, not necessarily whole 180arc counts required in that count. The Mechanics of Friction in Rope Rescue -Dr.Attaway In my words: Even as linear list/series of arcs on a...

    Bowline slippage

    Still only 5℅ loss is pretty dang good, but to purist theory and benchmark, pure inline again rules is witnessed again hear. . Logically, to have any bury, must have at least 1strand, and we now have that lower benchmark limit defined in this example, nothing could be 'worse' /less and still...
