00:00:00.040 --> 00:00:02.600 A:middle L:90%
problem. We have given diagram like this. So
2
00:00:02.609 --> 00:00:07.769 A:middle L:90%
for this problem, I suppose this line this is
3
00:00:07.769 --> 00:00:11.330 A:middle L:90%
supposed positive X axis. And this is positive y
4
00:00:11.330 --> 00:00:15.289 A:middle L:90%
axis. So we can say there are two component
5
00:00:15.349 --> 00:00:18.859 A:middle L:90%
of frost fn, fn X will be equal to
6
00:00:20.949 --> 00:00:22.890 A:middle L:90%
First of all, we will try to find the
7
00:00:22.890 --> 00:00:28.079 A:middle L:90%
magnitude of F one F 23. Okay, we
8
00:00:28.079 --> 00:00:33.240 A:middle L:90%
know that everyone f two and F three r are
9
00:00:33.240 --> 00:00:37.259 A:middle L:90%
the forces in the same rope so we can say
10
00:00:37.640 --> 00:00:40.920 A:middle L:90%
F three is connected here. Suppose the attention is
11
00:00:40.920 --> 00:00:43.750 A:middle L:90%
still so we know that this F three should be
12
00:00:43.750 --> 00:00:48.799 A:middle L:90%
equal to 4.25 and 29.80 That means it is equal
13
00:00:48.799 --> 00:00:53.780 A:middle L:90%
to 41.65 Newton or we know that after it should
14
00:00:53.780 --> 00:00:56.500 A:middle L:90%
be equal to F two and F one also So
15
00:00:56.500 --> 00:01:02.060 A:middle L:90%
we can write F one magnitude and F two and
16
00:01:02.070 --> 00:01:08.870 A:middle L:90%
F three should be equal to 41.65 Right, So
17
00:01:08.870 --> 00:01:14.060 A:middle L:90%
now we will right F one x everyone X will
18
00:01:14.060 --> 00:01:23.000 A:middle L:90%
be equal to 47.65 because theater minus 20 right?
19
00:01:23.010 --> 00:01:26.430 A:middle L:90%
We can read this now the direction of these forces
20
00:01:26.439 --> 00:01:30.150 A:middle L:90%
towards negative X axis in this direction. So we
21
00:01:30.159 --> 00:01:36.560 A:middle L:90%
we write minus and F one white will be equal
22
00:01:36.560 --> 00:01:42.810 A:middle L:90%
to 41.65 Signed heater minus 20. Yeah, like
23
00:01:42.810 --> 00:01:48.780 A:middle L:90%
this after will be equal to minus 41.65 because it
24
00:01:48.780 --> 00:01:52.840 A:middle L:90%
is already in the 20 degrees above the horizontal on
25
00:01:52.840 --> 00:01:57.189 A:middle L:90%
this plane. So this is minus 41 went 65
26
00:01:57.200 --> 00:02:00.150 A:middle L:90%
F two y will be equal to zero and F
27
00:02:00.150 --> 00:02:04.659 A:middle L:90%
three x should be equal to this is F T
28
00:02:05.239 --> 00:02:10.039 A:middle L:90%
. This is equal to minus 41.65 because of this
29
00:02:10.039 --> 00:02:15.360 A:middle L:90%
angle is 20 degrees, 30 40 degree cost 40
30
00:02:15.939 --> 00:02:19.340 A:middle L:90%
and f three. Why should be equal to 41
31
00:02:19.349 --> 00:02:23.219 A:middle L:90%
minus 41 65 signed 40 Because it is in the
32
00:02:23.219 --> 00:02:30.169 A:middle L:90%
downward direction in this direction three by. So these
33
00:02:30.169 --> 00:02:31.750 A:middle L:90%
are the component of F one, F two and
34
00:02:31.750 --> 00:02:39.780 A:middle L:90%
F three. So now we will equate. You
35
00:02:39.780 --> 00:02:44.349 A:middle L:90%
will quit the vertical component because f. N y
36
00:02:46.039 --> 00:02:51.050 A:middle L:90%
in that positive y axis in this direction and f
37
00:02:51.050 --> 00:02:57.310 A:middle L:90%
three y is in this direction. So these two
38
00:02:57.319 --> 00:03:05.310 A:middle L:90%
should be equal. So we will right 41.65 Sign
39
00:03:05.310 --> 00:03:09.340 A:middle L:90%
off. Tita minus 20. Should be equal to
40
00:03:09.349 --> 00:03:15.139 A:middle L:90%
41.65 Sign off 40 degree. So from here,
41
00:03:15.139 --> 00:03:15.939 A:middle L:90%
we can see if he does sort of equal to
42
00:03:15.939 --> 00:03:19.750 A:middle L:90%
60 degree. No, this is the value of
43
00:03:20.439 --> 00:03:25.310 A:middle L:90%
pita. So now we will right F net will
44
00:03:25.310 --> 00:03:30.150 A:middle L:90%
be equal to Afghan X plus f two X plus
45
00:03:30.159 --> 00:03:35.550 A:middle L:90%
f three x. I kept less f one way
46
00:03:35.939 --> 00:03:40.250 A:middle L:90%
f two y plus f three way Jacob So f
47
00:03:40.250 --> 00:03:46.240 A:middle L:90%
one x should be called minus 41.65 and this will
48
00:03:46.240 --> 00:03:55.830 A:middle L:90%
be equal to cost 14 minus 41.65 Cost 40 and
49
00:03:55.840 --> 00:04:01.629 A:middle L:90%
F two x is minus 41.65 Mhm and F three
50
00:04:01.629 --> 00:04:10.750 A:middle L:90%
X is minus 41.65 cars 40. Mhm. Mhm
51
00:04:11.639 --> 00:04:15.509 A:middle L:90%
. Okay, Graham, the icon direction now Vanuatu
52
00:04:15.509 --> 00:04:27.100 A:middle L:90%
is 41.65 signs 40. Yeah, after five years
53
00:04:27.100 --> 00:04:38.750 A:middle L:90%
035 years minus 41.65 Signed 40 Mhm. Okay,
54
00:04:39.540 --> 00:04:42.750 A:middle L:90%
so this is equal to zero. The objective direction
55
00:04:43.540 --> 00:04:45.660 A:middle L:90%
. If we saw this, this is equal to
56
00:04:46.139 --> 00:04:54.860 A:middle L:90%
minus 41.65 Yeah, two costs 40 last one.
57
00:04:55.339 --> 00:05:00.410 A:middle L:90%
So if we saw this, the net force net
58
00:05:00.410 --> 00:05:04.110 A:middle L:90%
force is equal to minus 106 Newton. The negative
59
00:05:04.110 --> 00:05:06.060 A:middle L:90%
X direction. If we talk about the magnitude,
60
00:05:06.540 --> 00:05:09.850 A:middle L:90%
this is equal to 106 Newton.
