    Rigging Physics 101 -- Redirect Pulley

    My (witnessed/self taught)take on lever trading between power and speed(distance) from the same finite volume of force: In rigid levers, if the static pivot is between the dynamic/moving input and output parts/positions, is class_1; only class_1 levers can reverse directions of input to output...

    Pulleys, to non-moving points are redirects only, they do not increase power or reciprocal distance(speed). >>Pulleys against Load divide it smaller for more power; >>Pulleys against Input Effort, divide it smaller, for less power, but 'extrudes' more reciprocal speed(more distance in same...

    A> Would look angled heavy duty beams SLANTED I'd think from frame, 120 or less spread, just like rope support, don't want flatter, want more teepee, more closed not flatter. If is 120 not 60 spread would want cross member between points hits frame across to each other to fight cross force. This...

    You got it! . Line tension X legs of pull per point . For purist view, Pulley on anchor does carry 2 X 1000 Line Tension BUT, is 90 degree spread, so 2 X 45 degree deflection from center. >>>>So anyway, more like 2 X 707 than 2 X 1000, pulling at angle too. Playing that backwards, if were...

    That small manual is chock full of using minimal tools, in most basic concepts. >>many scenarios are these basic skeletons with more fluff of this or that skin make-over; but all the same underneath if you squint right. i've never done the pickets per se, but have assessed many things by that...

    Winch will still only be as good as it's anchor/truck etc. Crane is only good as ground it stands on!! . You can pull and not burn up clutch so much by just using pull in it's power band, not screeching redline. To impact something can also run 15-20mph with clutch pushed in etc. when hit rope...
