These are the stressors that can make an otherwise simple task easy to become so much more complicated.
The stress is the stress.
When you’re working on something complicated, like a car or a piece of software, you’re dealing with a highly non-linear system, and the more you try to understand what’s going on the more complex it gets. An example of this is the stress you get from using a wrench on a car.
torsion is not a thing. It is a mathematical function that represents the degree of twist of a rope, in other words, the amount of twist of the rope going through an arc. If you look at the stress that occurs when you put a wrench on a car, you see it in terms of how much twist the car is going through.
This is a great example for how we can use math to look at big systems and make sense of them. The stress equation shows us a complex system in terms of the numbers of parts. Our stress equation, with the wrench on the car, shows us that the car is going through an arc, but that is also not necessarily linear. Our stress equation, or equations, also show us that the car is going through an arc, but that is also not necessarily linear.
In the trailer, the car is going through an arc from a straight line to a curve, but it is also not necessarily linear. We don’t really know what it is, but we know it is a car.
We know the car is going through an arc (we know it is ‘going through’ an arc because we know the car is making an arc), but we just don’t know what it is. The trailer gives us an idea, but we still don’t know.
The torsional stress equation is the equation that allows us to predict the car’s shape, but we dont know. In the trailer, we see the car going through an arc that is a straight line from a straight line to a curve and then back to a straight line again. We dont know what the curve is, but we know it is a straight line. We dont know what the curve is, but we know it is a curve.
I think we can see a pattern here; the most common pattern is a straight line, then a curved line, then a curve. But we don’t know the underlying structure of the curve; we don’t know how the curve affects the car, or the angles of the car, or the shape of the car, or whatever.
