Thoughts on "Triaxial loading of a belay loop, waist belt, leg loops"?

What in the world does that mean?  How about not ending sentences with a preposition?

I think he's just pointing out that the world in which we live has 3 dimensions not 2, although it is arguable that our world actually has 4 dimensions with the 4th being time. To which I say, this is a climbing forum, not an engineering/physics/mathematics forum, so perhaps using climbing jargon might be better than engineering et al jargon.

Time isn't a dimension. My goal in life is to find a way to disprove it. If something moves in x, y, or z we can see a change. You can't see change in time all you see are two different objects moving in x, y, z and use the difference in how the 2 moved something called time. We take watch or some other device that moves at a constant rate and we look at that movement and call it time to compare movement of other things.

This works on the assumption that time is constant, which it isn't. Ever heard of time dilation? Unfortunately Stephen Hawking isn't with us anymore to explain it to you.

Wrong again. Does anything in the universe take place without time. Clearly, you have no physics background.

Time isn't constant or should I say movement isn't constant another reason why it doesn't exist. Where things are in this world affects their "time" but it is really just objects affecting the movement of other objects.

People used to think the world was flat at one point also. Just because you think this imaginary time thing exist doesn't mean you just don't have complete understanding on how objects move in this world.

Come on Viper...You're going down a silly path. Sensible thing to do is turn around not beat your way further down it ;P

Ok how do you prove time exist?

You don't.

The irony in that statement.

How long will that take?  How do we measure the increment that you will use to disprove it? Time, as a dimension is ordinary knowledge.  Has been for decades.  

Time as a dimension predates Stephen Hawkins by a many decades.  Time dilation, twin paradox, Lorenz transformatiion....,  proven many decades ago.

Would you prefer to biaxial, triaxial, gayaxial, heteraxial load your biner in 1/100 of a second or 75/100 a second?

Everything you just said supports disproving time... however it is all relative so really doesn't disprove time but supports disproving time.

Don't be a jerk.

If you have some engineering expertise that makes you qualified to comment on the triaxial loading terminology as used in climbing, that's great and helpful. You clearly don't have the background in physics to make this statement, and it's super hypocritical to rag on folks for incorrect understanding in an area that you have studied and then turn around and do exactly the same thing.

Are you referring to the general theory of relativity or the special theory of relativity?  Take your time responding.

If dangling a preposition was good enough for Shakespeare, it's good enough for the likes of you, you damned dirty Drydenist...

Draw out the free body diagram and the component vectors.
