Math Question

[Fabrik8]

And here's the rest for the cable solution with the cable at 90 degrees to the pole; summing moments about point A.

I'm just using the component of the weights that are perpendicular to the pole, because moments are a perpendicular force applied at a distance (basically a torque).

Notice how the two weights of the pole (W1 for triangle and W2 for rectangle) are just two parts of the moment summation, super easy. No need to combine them, like I said before.

If the cable was at some other angle to the pole, there would just be an added "sin(whatever angle)" after the cable tension, similar to the weights.

Understanding the problem is the hard part, after that the math is usually pretty straightforward.

Holy hell thats awesome. I'm going to have wait until after work to digest this a little better. What is the name of the process so I can look up some more information on this?

It's a 2-dimensional static equilibrium problem, using equilibrium equations.

Here's the rest of that puzzle, from the previous page:

White privilege bolstered by teaching math, university professor says

are you folks not aware that solving math equations is the equivalent of practicing white privilege?

Gotta read your own thread bro!
