The cable almost certainly provides resistance. So what your feeling is likely that, not force. That "cable resistance" is not a force? :shock: Not a productive force. Let me put it another way… My knees are stiff. There is resistance in knee joint articulation. Does this mean I can leg press any b...

That "cable resistance" is not a force?

There is no torque. Torque is the product of unequal forces. The cable forces sum to zero. What? You think a force and a lever do not create torque? The spring is creating a force on the binding (trying to lift the rear of the binding up), and the same but opposite force on the boot (trying to lowe...

I agree with all those things. Every single one. The binding, boot and cables are a closed system however. Whatever force the cable exerts on the back of the boot is opposed by an equal and opposite force holding it to the rat trap. (Your diagram appears to show a sliding binding, which is quite di...

Any guesses why NNN BC bindings don’t use cables? If the cables transferred force, surely they’d be useful… But cables don’t transfer force. They control heel movement. So why don’t NNN BC bindings use cables? Look at the bottom of the boot and top of the binding… 8209E8E6-5CA1-49FD-AA37-8EC43F9E1F...

I have a feeling that this whole topic is full of partially deliberate misunderstandings about the semantics

We all understand how the bindings work, how the skier is the source of all energy etc. but we can't agree how to describe it

Bindings facilitate the shifting of weight. They don’t actually shift weight themselves. The skier does that. A binding element attached to itself cannot generate pressure. The forces act in equal and opposite directions, as the laws of motion require. Well, you are correct here on both of your sta...

Here’s a way to confirm Newton’s Third LAW of motion… Remove a NN/3 Pin binding from a ski. Lock the bail onto a ski boot duckbill. Hook on cables and place them over the heel of the boot. Put the boot down on a flat surface. Does the boot move forward on its own? Of course not. That would be impos...

Great to hear from you again Verskis! Bear with here- trying to understand your original question and objective- My understanding is that you want to make linked turns on groomed hills at the groomed Nordic track- correct? A question- do you have to be able to make actual equally-weighted telemark ...

Grimsurfer, since you can make a freebody diagram, try to make one where the heel is raised with a cable binding (for the simplicity of reading the diagram, you can exaggerate the distance from the bending point of the duckbill to the attachment point of the cable. The principle will stay the same, ...
