Thanks Jim,
That makes 100% sense, was wondering where the "Magic" 2x and 4x came
from, as I was expecting to see a COS in there somewhere, and moment
arms (I know enough to know that)
It may seem that trigonometry is always necessary to make these
calculations. However, in many cases, the forces can be determined
without trigonometric functions by using similar triangles. There
is a tendency to jump right in with trig functions whether they
are essential or not.
