Find the numeric value of t1 in newtons.
00:03
Okay, so we're given alpha and we're given beta.
00:09
Let's find our expression for our sum of our forces in our x direction.
00:14
We have tension 2, cosine of 26 degrees, minus tension 1, sine of 19 degrees, equal to 0.
00:22
So we can go ahead and substitute.
00:24
We find tension 2 is equal to, we can divide our sine of 19 degrees by our cosine of 26 degrees to get 0 .362 times t1.
00:38
Now in our y direction, we have tension 1 times cosine of 19 degrees, plus tension 2, sine of 26 degrees, minus our weight force, equal to 0.
00:50
So plugging in our value for tension 1, or plugging, yeah, so let's plug in our value...
