07:53Parabola

07:55In the case of Parabola, we need to know

07:57what is Parabola

07:59or how to determine the shape of Parabola

08:01In this

08:03we are going to draw Parabola

08:05in a rough way

08:07I am enlarging it

08:09This is the Parabola I am drawing in a rough way

08:11If we draw Hyperbola, we will be drawing

08:13Parabola in a rough way

08:15In this, two things are given

08:17Parabola with maximum

08:19ordinate 20

08:21What are the data of Parabola?

08:23or which are the data of Parabola?

08:25we need to know

08:27For that, Parabola

08:29I am going to tell you some data

08:31of Parabola

08:33You may already know the data

08:35but still I am telling you

08:37For a Parabola, there is a term called Vertex

08:39Similarly, there is a term called Ordinate

08:41or Double Ordinate

08:43If I draw a Parabola

08:47This is a Parabola

08:49This is a Hyperbola

08:51If I draw a Parabola

08:53from top point to middle

08:55this is the height

08:57of Parabola

08:59This is the height of Parabola

09:01Top point is called

09:03Vertex

09:05Similarly

09:07The distance between

09:09two points is called

09:11Double

09:13Double

09:15Ordinate

09:17Double Ordinate

09:19Half distance is called

09:21Ordinate

09:23Ordinate

09:25Don't forget

09:27Total distance is called

09:29Double Ordinate

09:31Half distance is called Ordinate

09:33Half distance is called Ordinate

09:35This is the height

09:37Top point is called

09:39Vertex

09:41If we utilize the same data

09:43Parabola with

09:45Ordinate 20

09:47Parabola with

09:49Ordinate 20

09:51I drew a line in the middle

09:53I took it as an edge

09:55The height is true shape

09:57The distance from here to here is

09:59V1

10:01V1 is from this point to this point

10:03We have to find V1

10:05We have been told

10:07Maximum Ordinate 20

10:09Ordinate means

10:11Half of this is Ordinate

10:13Ordinate 20

10:15Ordinate or Double Ordinate

10:17Ordinate is

10:1920 mm

10:21Double Ordinate

10:23Total distance is

10:25Double of 20

10:27Total distance is

10:2940

10:31V1 is equal to

10:3340

10:35We got two things

10:37V1 is equal to 40

10:39We are going to draw

10:41True shape is Parabola

10:43How to cut

10:45Parabola

10:47We are going to fix V1

10:49We are going to fix V1

10:51We need 40

10:53Fix 40

10:55Take the scale

10:57Vertical distance

10:59We already know the diameter

11:01Diameter is 50

11:03Always

11:05Vertically 40

11:0740

11:09Stop

11:11Stop

11:15We got

11:1740

11:19Fix

11:21Fix

11:23Vertical

11:25Vertical

11:27We got 40

11:29Fix

11:31Fix

11:33Fix

11:35Fix

11:37is in between G and F and point 2 is in between C and D so GF is in the base and 1 is in between

11:48C and D. So I extended both the points vertically. I have 2 points 1 and 2. 1 is in front and

12:002 is behind. So 1 dash behind and 2 dash. So I have to cut from here. So I have to cut

12:06the soldering from here. How to cut is the next question. I will zoom in so that you

12:12can see. How to cut is the next question. So we have to start from 1 and 2. Now we have

12:20to know what is a true shape. It is a parabola. So to get a parabola as I said in the introduction

12:26video. Either we have to cut the generator on this side or this side parallel. Now this

12:34point is nearer to this generator. So what we have to do is we have to parallel scale

12:42the generator on the right side and move it. If we draw a parallel line for that what

12:48we will get? True shape will be a parabola. So that is how you have to section the generator.

13:02What is special about sectioning is that the section plane is parallel to the generator.

13:12So we have got a parabola. Now we have to give name to the cutting points. I have already

13:20cut 1 in front and 2 behind. When we move from here, the next point is in the middle.

13:26It is not the axis in the middle. There is a generator called NCNG in the middle. It

13:34is divided into 8 parts. There is a generator called NCNG in the middle. So we have to give

13:42name to that generator. So 1 is behind and 2 is in the middle. There will be 2 points

13:52in the middle. I am giving a bracket for the 3rd point. There will be 1 point in the middle

13:58and 1 point in the middle. That means 3 dash is in NCNG.

14:02Now we have to give name to the 4th generator. There will be 2 points in the middle.

14:08There will be 2 generators called NBNH. So we have to give name to the 4th generator.

14:18Now we have to give name to the 5th generator.
