damn, I knew force doubles because of the 180 change in direction of the force vectors but I would have assumed that in both causes it would double! So in redirect situation, one can pull a much heavier vehicle without anchoring your vehicle as long as the heavier vehicle is not less than twice the weight of your vehicle. It makes sense that the pulling weight at the snatch block would double since one point is fixed and you have an action and reaction forces that add up. you have the 1000 kg force traveling from the 1000kg truck all the way to the fixed point on the ground, cable tension = 1000 kg BUT around the snatch point it changes direction, thats where it adds up. Just mind boggling to think you are creating double the force from nothing, right? I don't blame the lady 🙂. With double line since both the fixed points are on the truck itself, the weight of the truck is split equally and the tension the line feels is 1/2. Here you are basically doubling its capacity at the expense of speed.

I see a risk of people getting this wrong. If you are pulling external load attached to snatch block, other end don't need to be attached on solid object. It can be attached to the vehicle and the force is still doubled. Of course if you use solid object, you vehicle needs only half of the force to anchor it into place.

This is great thank you. I watch a lot of your videos and try to study them....given this logic it makes me wonder, why bother doing a redirect if you're not getting a mechanical advantage? Why not just hook right to the first anchor point? I suppose it could help to get to lower levels of the rope which produces more power from the winch.

take your time and re-rig as required

To undertand the forces here think about this. Attach the snatch block to the rear of a Towing Car (Car A). Don't Actualy Do This, Only In Your Head. You will FAST understand why. If both ropes are connected to the car being towed then the setup is the same as a single line pull (Car B) Energy Needed to move Car B 1kmh = 1 x E Now connect one rope to a Tree next to Car B If Car A travels at 0.5kmh then Car B will travel 1kmh Or if Car A travels at 1kmh then Car B will travel 2kmh and Car B will be getting 2 x E. Also here the Tree is also working at 2 x E And Car A and Car B will combine to become the latest viral video. So if Car A wants to stop Car B from reversing, Car A now needs 2 x E brakes to stop Car B reversing Because Like the Winch setup, (Car B has a Winch) and now only needs half the Energy to pull Car A in reverse. Car A = Car B + Tree The Pulley on the Ramp is giving the Toy Car a 2:1 advantage to pull on the Scale with so the scale reads 2 x Toy Car. And this is how to better understand what E=MC2 Actualy means. E = Speed of light, M = Car B, C2 = Winch Wired to a Dwalf Star Held inside a TARDIS.

Best setup is to attach the snatch block to the vehicle being recovered and run a buddy's winch through it to an anchor.

Joking aside, the force applied to the anchor is half of that that would be applied by attaching the snatch block to the anchor and running the cable back to the vehicle being recovered. I prefer to have the pull capacity of the winch to be the weakest link. That way I don't have to worry about cables snapping, shackles breaking etc. I don't exceed the working load limits of these components (I can't because the winch capacity is less than the working load limit). The problem is that I have yet to find a tree with the working load limit posted on it. So if I can figure out a way to halve the load on the tree, I think that is better. You can also use another vehicle as the anchor point, using recovery points on it whose working load limit exceeds the capacity of the winch.

Watching his rigging and his techniques for moving something the way you want it to go is very educational. Your video was excellent also -- it puts some real world data into it. I never appreciated how much the load on the cable can vary during the recovery and how fast it can change. It is those fast changes that could result in the failure of a component, even though the actual load on the component does not exceed its rating. Lesson learned: take it very slow and easy when working at the limits of the capacity of your equipment.

As far as vehicle winching, this video seems to miss the crucial point. The point of winching the vehicle with a snatch block back to itself is to reduce the load on the winch. And you've shown that the load on the winch is indeed halved. In fact, you've demonstrated that you should not winch from the vehicle to a second static object, because you are towing twice as hard on your winch point in front of you. So if it's a tree it's taking twice as much load as it needs to and the load on the winch is the same. Instead you want to winch from the vehicle to the snatch block at the tree back to the vehicle. Now if you're trying to tow a stuck vehicle in front of you you would absolutely benefit by going from your vehicle to the stuck vehicle to a solid tree.

I'm not getting the point of what you're saying because (I guess) I'm stupid. But I thought the point of using a snatch block is to make your winch not have to work as hard. So why are we focused on the amount of pull against the tree? In other words, why is the meter where it is instead of measuring the tension in the piece of rope connected to the winch? If I'm in a stuck car, I'd want to know if what I'm doing is making the winch's job easier or not. Another stupid thing I'd like to contribute is: since the snatch block doesn't move then it only redirects, so how the heck is attaching the other end to an anchor contributing anything to the situation the vehicle is in? As I understand it, using a moving winch is when the advantage happens. Have I learned everything wrong? Upon further reflection, maybe this is a demonstration of an incorrect setup. Because as I understand it, the moving winch needs to be attached to the stuck vehicle and this setup only pulls harder on the tree and does nothing to help the stuck vehicle.

Your commenter is right. The issue is that you're confusing weight and force. The reason (I suspect) is because of the imperial system measuring force in lbs. Anyway, to make clear the difference, something still has a mass when you're lifting it, even when it's not putting any force on the ground, and a vehicle doesn't double its weight when you run a double line pull, or half when you split a double line pull between the vehicle and an anchor.

Your weight changed because you went from one line supporting the full load, to two lines supporting the full load, not because your angle changed. The correct test would be have an inline anchor not connected to vehicle. Now if your test was to see if a vehicle mounted wench makes a difference, then yes the anchor on the vehicle matters.

Yes, that commenter is wrong and the author of this channel is mechanically correct. They are still both semantically wrong. What is this "creating weight" nonsense? Weight is a measure of heaviness - it differs from planet to planet, even though an object has the same mass (which is a measure of inertness - in "weightlessness" objects are weightless but not "massless", but in most practical situations we tend to think of weight and mass as interchangeable, like speed and velocity). Pulley/block is one of "six simple machines" - a historic sign of civilization (along with "inventing the wheel"). To deny that pulleys provide mechanical advantage (aka "leverage") is to also deny wheel and axle, the lever, etc. And to deny human civilization. It is not "creating weight", or even changing it, it's merely splitting applied forces and sharing them across directions. Just like leverage. Words mean things, otherwise everything would be a dohickey or a whatchamajig.

You are confusing force at the pulley vs. mechanical advantage. I agree you have 6.2 Kg. But that is the force at the pulley. You have to have a moving pulley to have a mechanical advantage. The setup you show is simply a redirect.
