    Marlow Vega Availability?

    ha! Okay, disregard. Just coming out of Christmas and it's still on my mind

    Marlow Vega Availability?

    I only ever bought the orange; was afraid the green would blend in too well in the summer.

    Marlow Vega Availability?

    Ah cmon man..."I'm doing just fine, Clark". Eddie in Christmas Vacation. You're the one who originally put me onto Vega! Thanks.

    Marlow Vega Availability?

    Do you concur with the "stiff", almost-non-fuzz feel of the Vega jacket? Is that in any degree reflected in the Allgear 11.8 poly/poly's?

    Marlow Vega Availability?

    Yeah it's good, but not worth that. I'll be just fine, Clark, with some hyperclimb or km3max.

    Marlow Vega Availability?

    Thanks for the word, oak. I'll take a look. I have one hank of Vega and it is awesome - love the feel of the jacket too; very stiff, etc.

    Marlow Vega Availability?

    I won't claim to be a black belt in Google/DuckDuckGo-fu, but I *am* having trouble finding Marlow Vega from any US sources. Anyone got a lead on that stuff? ~200' of it?

    Man, I've tried, but I don't think I'm following. Some of the terminology is throwing me... If this is saying that the measured output force was greater than twice the input, is that due to friction/nonideality helping? That is, if more than the nominal input force was applied temporarily...

    Predict the pull

    I gotta go through and see how it changes things exactly when the double pulley on the load side is also used as the anchor ("folding the anchor back in", as you say); I'm unsure why I didn't analyze this way to begin with, as this is how, of course, every one of my 5:1's are set up. All about...

    It is wild how convincing it could be based on how it presents its results, if you didn't look closely at the numbers.

    Predict the pull

    100%. Agree. From post #52: output mass = (input mass) × (effective MA) (input mass) × (MA_ideal × efficiency) [[[25kg × [5:1 × 0.85]] × [5:1 × 0.85]] × [5:1 × 0.85]] = 25kg × [5:1 × 0.85]^3 = 1919.1kg

    Predict the pull

    I'll letcha hold a dollar if what he was originally envisioning is not like this (except 3 cascaded systems instead of 6)... Each system is a 5:1 and is connected to an anchor. All of them could possibly be connected to a rigging plate which is then connected to an anchor, or something along...

    Are you referring to this? I think he was just saying that he's consistently applying 50kg to the input leg of the entire cascaded system as he subsequently adds stages.

    Predict the pull

    He's definitely cascading/piggybacking them, since not only does he say "5:1 on a 5:1 on a 5:1 on a 5:1..." and not "5:1 with a 5:1 with a 5:1..." And to confirm this, the ideal output MA for 6 cascaded/piggybacked 5:1's is indeed 15,625:1, as he noted. Six parallel 5:1's would end up being...

    Predict the pull

    This is saying that the overall efficiency of the 125:1 system is 85%, NOT that the efficiency of each of the three stages is 85%. If each 5:1 stage was 94.7% efficient, then cascading 3 of them together would yield a 125:1 system that is 85% efficient overall. If each 5:1 stage was 85%...

    I'm feeling way less threatened by AI now. Thank you. Edit: actually, you just trained it! Go ahead and encourage its wrong answers :LOL:

    Predict the pull

    To be a little more explicit, the second diagram is 6 systems being cascaded or "piggybacked" to one another. The math for 3 cascaded systems each having 85% efficiency would work out in expanded/verbose form as such: Fout1= (Fin) × (MA1 ideal) × (efficiency) = 25kg × 5:1 × 0.85 = 106.25kg...

    Predict the pull

    So this is the system you intended to have it calculate? ...and not this (but with 3 stages instead of 6)? It's wild - the AI's decimal places are still off and, in my opinion, its explanation is kinda all over the place. I actually think for at least one of those "stages", it's using an...

    Predict the pull

    Can you ask it to show its math? I'm not getting anything that agrees with this, and with it being a "black box" (that is, we can't see what's going on inside), there's no way to see how it's arriving at its conclusions. It's not treating each pulley as 85% efficient, it seems, but rather each...

    Predict the pull

    Here's where curiosity, a little thinking, and some time after putting the littles to bed got me... This deals with a 5:1 system, but is easily expandable. The more general form for this architecture of mechanical advantage arrangement - meaning a simple system, non-piggybacked - would be...
