Force Relationships

[TheTreeSpyder]

Carried over; as not to hijack LuvNick's Pull Question Thread anymore....; i have continued this avenue of thought/discussion'ere.


i think that in Nature, that the macho vision of what is happening with just 1 singular quanity is not write. Rather, everything is more fo a female view of relationships of the forces to each other. In what Glens and i been volleying back and forth; my position is such. That the mechanichs is not dependant on what is happening with just 1 end of the line; but it's opposite too.

Because the Equal & Opposite (E&O) reaction is required from anything; many times the limit of force we can place on something; is the limit of the E&O.

Non-linear force, takes a longer path than linear; therefore can work the distance multiplier higher, for more power.

Even studying/living the simplest of movemeants, provides oppurtunities for understandings and applications, for all works the same.

Most powerful are the force arraingemeants that oppose each other, but, yet without butting heads of these forces. For this gives the most non-linear/tourqued forces.

Here, are these things applied to hinging. Hinging usually is both sides open, then both sides closed, generically. i like hinges that are specialized to task; especially in climbing.

The task is, where you want it to go as target, in relation ship to the lean force/where it wants to go. So, to me, generically closing both sides at once, is not maximizing the scenario to the specific task. A tapered hinge (not handled here) is one way to do this, in tandem with these strategies.

Here a 2/1 with a come-a-long, but the pulley for 2/1 is on the anchor device, and not load. Here the force value of the CAL that usually pulls on the anchor and terminates, is now recycled to pull on the load. Thus, we have the force of CAL and it's E&O put to work focussing on the target load.

2Handing a Rig Test shows 1 of the test runs proving how 2 handing works. i used a comealong pulling 500# on a Dynamometer; and how returning it's E&O pull through a pulley and on to the load instead of terminating that pull at anchor; gave 1000# pull on the other dynamometer. The setup is like in the #2 scenario in the picture attatchmeant above.

2Handing Powers shows using 2 handing on compounded pulley systems. Like 2 handing a zrig, inset inside of a 5:1, so that both ends of the Z pull actively on the 5:1. In this way, you 2 hand the Zrig, and it essentially 2hands the 5:1 it is inset inside of. The output is 32x 1 hand's pull; though using 2 hands.

I love how you love this stuff.

Spydie, everywhere I go I see ropes and pulleys lately ... do you have a fetish?

Well, I'm confused. Information overload.

If one handing is say 5x and two handing is for some reason more, what happens when I hook up my 4WD?

We need to get this 2 handing thing sorted first.

Hey Ekka after you've known Ken for a while you will see that "fetish" doesn't even scratch the surface! /forum/images/graemlins/grin.gif
