So for this problem, we have a box that is being held stationary.
00:04
And it's important that this box is held stationary because that tells us that's in static equilibrium, which means that its net force is therefore zero and it is not accelerating and it's not moving to begin with.
00:15
So we're going to draw a dot to represent the box.
00:18
And the first thing we're going to do is we're going to draw a force down that we'll call fg.
00:23
This is force of gravity.
00:26
Grab the axe straight down on the box.
00:28
Now we're also going to draw a straight line going up just for reference.
00:31
For the vertical and now we're going to draw the first force of tension from the cable.
00:38
This will say is a 10 degree angle i know it's definitely not exactly a 10 degree angle but as long as we label it as being such it works out fine.
00:49
So this is force of tension 1 is what we'll say.
00:52
Now we'll draw a second vector that knows is identical in magnitude at a 10 degree angle on the other way and we'll call that force tension 2...
