There are three forces f1, f2 and f3.
00:07
This is x -axis, y -axis.
00:11
The three forces are this is the force f1, this is force f2 and this is the force f3.
00:26
Now the distance of the f1 from the origin is 70.
00:33
Distance is 240.
00:39
Distance of f2 is 210.
00:45
Distance from the x -axis of f2 is 200.
00:50
Distance of the f3 from the x -axis is 225.
00:56
This distance is 170.
01:02
Magnitude of the force f1 equals to 500 newton.
01:07
Magnitude of the force f2 is 435 newton.
01:13
Magnitude of the force f3 equals to 510 newton.
01:19
When this is angle theta 2, this is angle theta 3.
01:24
First we will calculate value of theta 1, theta 2 and 3.
01:29
Then theta 1 equals to tangent inverse 240 upon 70.
01:35
It gives value 73 .74 degree.
01:42
Value of theta 2 equals to tangent inverse 200 upon 210 equals to 43 .60 degree.
01:55
The value of theta 3 tangent inverse 225 upon 120.
02:04
It equals to 61 .93 degree...
