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.
