Playing with Dutchman Forces while Climbing

More examination on how i think mechanics of hinging can be adjusted; brought into the tree while climbing.

Trying to get least load and most support at end. A hinge just being a responsive force to the loading, is set to match strength to the loading at first folding. If leverage is decreased, holding fiber amount must increase, until Leverage X Pull = Load (or just short of to get off balance to allow movement). So, any arraingement is about equal at that point/function, as leverage distance increases, pull reciprocates and drops, until hinge response is again Leverage X Pull = Load.

Shifting the pivot is so powerful; 'a pivotal change' is a part of the language; to signify immense, crucial etc. adjectives.

A vehichle running head on into a concrete embankment that doesn't give or crack, is equal to that vehichle impacting it's mirror twin in speed, weight etc.; placing the equal and opposite forces confronting each other in 1 space, not at 2 different ends like pull force. This makes dutchman use more powerful and dangerous; also there must be enough force to throw through the closure cleanly and you could increase disconnected force etc. that can be dangerous.

Dutchmans can be dangerous, are outlawed in logging camps etc.; but climber's commonly use a snap cut on horizontal, or hop a top with same from a vertical position of smaller than tree force size uses. These are kerf dutchmans. Placed in lean side of face only(inside normal face), can form a step dutchman that closes that side's face immediately(make on lean side). Whereby a dutchman with a tiered face (as in attatchment)to form a step dutchman(as opposed to jsut kerf as step) can allow so much 'X' movement forward to clear obstacle and/or build speed force, before engaging the step push off (to get push/lift must have enough force to throw cleanly thru step and not stall).

Or something like that.

All ways trying!

Another view, of sweeping horizontal limb across, perhaps into rig. Then adding different types of Dutchman Force to give helpful push up to lighten load and/or more leverage after the forcing of the initial higne strength at First Folding.

The Hinge Strength on it's direction of movement will always initiate the same, to the same Center of Gravity(CG) pull; but, then you are stuck with the hinge pull fibers and face for the rest of the folding. Resistance in face can be dangerous if miss-used; but if enough force is gathered to throw thru the resistance, this can give helpful push up (to 'lighten' load); or pivot change.

The Dutchman's invoke compression force that concentrates more force in one spot than tension support force, so can be more dangerous as well as helpful, and outloawed in some cases, especially in the sheer levrage, force and speed compounidng multipliers in full tree felling force ranges.
