00:00:00,690 --> 00:00:01,470
‫Welcome back.

2
00:00:02,220 --> 00:00:11,760
‫We talked in the past that when, for example, model one rotates counterclockwise like this, then

3
00:00:11,760 --> 00:00:16,320
‫that makes the drone rotate clockwise.

4
00:00:17,460 --> 00:00:23,220
‫And now I want to make something clear now, I'm not talking about the thrust force.

5
00:00:24,470 --> 00:00:29,600
‫A thrust force would be the force factor that would.

6
00:00:30,590 --> 00:00:37,220
‫In this picture point towards you, so that would be the upward vector.

7
00:00:38,590 --> 00:00:47,800
‫But now I'm not considering the thrust force now and considering the talk that the drone applies to

8
00:00:47,800 --> 00:00:49,600
‫the rotors to rotate them.

9
00:00:50,630 --> 00:00:58,550
‫And then when the model rotates, then, of course, thanks to the blades, shape and thrust force is

10
00:00:58,550 --> 00:00:59,300
‫generated.

11
00:01:00,180 --> 00:01:09,120
‫But in order to make this rotor, rotate the drone, apply some kind of talk to this rotor, and so

12
00:01:09,120 --> 00:01:12,060
‫you will also have some kind of talk for M-2.

13
00:01:13,090 --> 00:01:22,510
‫And three and four, and so if you know how much talk is applied to each model, then you can add them

14
00:01:22,510 --> 00:01:30,580
‫up like this talk and one minus talk and two plus.

15
00:01:31,780 --> 00:01:34,090
‫Two and three and minus.

16
00:01:35,310 --> 00:01:38,340
‫Talk M4, and that would equal.

17
00:01:39,540 --> 00:01:48,420
‫Your network or moment, the same thing applied to the propeller's by the drone.

18
00:01:49,670 --> 00:01:58,220
‫And whatever value you get here, either positive or negative, the drone itself then experiences the

19
00:01:58,220 --> 00:02:03,140
‫same talk, the same network, but in the opposite direction.

20
00:02:04,220 --> 00:02:14,960
‫And so the reason why you have a minus sign here and the minus sign here is because more M-2 and for

21
00:02:16,130 --> 00:02:18,730
‫their Maurer's rotate clockwise.

22
00:02:18,920 --> 00:02:24,680
‫So according to the right hand rule, your thumb would point into the screen.

23
00:02:25,800 --> 00:02:33,840
‫And so in case of more one and more a three, your thumb would point out of the screen because you are

24
00:02:33,840 --> 00:02:38,350
‫rotating counterclockwise and then your talks would be positive.

25
00:02:39,570 --> 00:02:45,240
‫And so if your network is positive or counterclockwise.

26
00:02:46,340 --> 00:02:50,960
‫The network applied to the murders by the drone.

27
00:02:52,030 --> 00:03:00,400
‫Then the drone itself would experience a clockwise talk, and if the network is clockwise, then the

28
00:03:00,400 --> 00:03:04,690
‫drone will experience a counterclockwise talk.

29
00:03:05,630 --> 00:03:12,230
‫Because it's equal in magnitude, but opposite in direction, just like we saw it with the helicopter

30
00:03:12,230 --> 00:03:14,120
‫example at the beginning of the course.

31
00:03:15,470 --> 00:03:27,380
‫And so now what we want to do, we want to relate the talk applied to the murders by the drone, all

32
00:03:27,380 --> 00:03:29,460
‫these four talks here.

33
00:03:30,500 --> 00:03:34,910
‫We want to relate them to our AmeriGas.

34
00:03:35,940 --> 00:03:36,970
‫Respectively.

35
00:03:38,040 --> 00:03:39,650
‫So let's see how we are going to do it.
