05:06You can cut off the section top view by goods.

05:11You can cut off the section top view by goods.

05:16You can cut off the parking lot with goods.

05:21You can save your data as usual for next.

05:26You can save your data as usual for next.

05:31If you don't have space, you can use this line as a base line

05:38I am drawing a parallel line here

05:41I drew a parallel line

05:44Then I am taking the perpendicular

05:46Perpendicular from 1 and 2

05:50Perpendicular from 1 and 2

05:54Then perpendicular from 3

05:59Now take the compass and mark the distances

06:02First distance

06:04Distance from 1 to section point 1 in the x-ray line

06:08If you have drawn a new line in the perpendicular line from 1, you can mark it there

06:13So you will get first point 1

06:15Then second

06:17Distance from x-ray line to 2

06:21I marked a new line in the perpendicular line from 2

06:24So I got 1 and 2

06:26Distance from x-ray line to 3

06:30I marked a new line in the perpendicular line from 3

06:35I got 3

06:36So these three points

06:38This is point 1

06:40This is point 2

06:42This is point 3

06:43If you connect these three points, you will get the triangle with maximum base and maximum

06:49This is the triangle with maximum base and maximum altitude

06:55Mark the two shapes

06:59Maximum base and maximum altitude is a given data

07:04It is like a value

07:06Maximum base and maximum altitude

07:09To get the maximum base

07:12I fixed it between 1 and 2

07:14I tied it up and down

07:17I drew a section from here to here

07:20This is the edge

07:21If you want to get the maximum edge

07:23If you want to get the maximum edge, come to point 3

07:25This is the edge

07:27This is the edge

07:30If you cut it here, the edge length will be reduced

07:34The maximum you get is in this point

07:37You have to hide the remaining portions

07:40This is the remaining portion

07:45This is the remaining portion

07:49This is the remaining portion

07:53I cut the portions

07:54The second part is 32B

07:58The specialty of 32B

08:00This is the triangular prism

08:05The true shape is

08:07A triangle with base 32 and altitude 50

08:11You have to pay attention to the question

08:13In 32B, the base is 32 and the altitude is 28

08:18We can't do the question with 28

08:20Please correct the question

08:22Base is 32 and altitude is 50

08:25We can't do the question with 28

08:29We can do the question with any value above 28

08:31I took 50 value randomly

08:33It is difficult to do in 28

08:35We are going to do this

08:36We drew a triangle here

08:43We have to fix the height

08:47This is the edge

08:49As usual, the perpendicular distance is V1

08:52The triangle with base is 32

08:55V1 is equal to 32

08:57In the previous case, V1 was maximum

08:59In this case, the value is 32

09:01In the previous case, the edge is maximum

09:03In this case, the value of the edge is 50

09:06H is equal to 50 and V1 is equal to 32

09:09When I said maximum, I fixed the maximum between these two lines

09:14It was between these two points

09:16Here, the value is 32

09:19Here, the value is 32 vertically

09:21Keep the scale and measure between these two lines

09:25The length of this is 40

09:26The base edge is 40

09:28When the base edge is 40, we can't do this

09:34When the base edge is 40, the maximum value is 40

09:41If the value is 32, move the scale parallel

09:44When the base edge is 32, we can't do this

09:49Fix the value

09:51We can fix the value

09:53This is the first point 1

09:55This is the second point 2

09:58The value of 1 and 2 is projected upwards

10:00The value of 1 and 2 is projected upwards

10:03I projected it upwards

10:05I got the value here

10:07The value of 1 and 2 is projected upwards

10:13The value of 1 and 2 is projected upwards

10:15We need the third point

10:17We need the third point

10:19In the previous case, the maximum value was here

10:21In this case, the maximum value is here

10:23We need the third point

10:25We need to cut the C3 line to get the triangle

10:28To get the maximum height triangle, we need to pass 3

10:31This is the question we did earlier

10:33We need to pass 3

10:36This is not the maximum value

10:38This is the height value

10:40Altitude is 50

10:42How much is the altitude?

10:44It is the length of the edge

10:46We are going to cut from here to here

10:48Take 50 in the compass and cut

10:50That means

10:52Take 50 in the compass

10:54Take 50 in the edge value

10:56Then

10:58Keep this point

11:00Cut in this line

11:02We will get the length h50

11:04We will get the length h50

11:06If the length is h40

11:08Take 40 in the compass and cut

11:10We need to take the altitude

11:12We need to take the altitude

11:14We got the value here

11:16This is the third point

11:18We need to pass 3

11:20We need to pass 3

11:221,2

11:24We need to pass 3

11:26We need to pass 3

11:28We need to pass 3

11:30But we need to pass 3

11:32We were passing them

11:34We passed them

11:36And here

11:40We must also pass the remaining section

11:42Here we need to pass these

11:44We need to pass these

11:54It is not a full triangle

11:56It is small triangle

11:58So this will be the sectional top view.

12:01When you hatch the remaining section, remember that this is the only portion in the front view.

12:06The portion above this has been cut off.

12:09So you have to show the base.

12:12Then show this length.

12:14Along with that, there is one more thing.

12:17This point is only from here to here.

12:20That's it.

12:20The rest of these portions have been cut off.

12:24This was because the height was 50.

12:27If the height is 40, you have to take 40 from here and cut it.

12:29If the height is 20, you can't take 28.

12:32If you take 28 from here, you won't get 28.

12:34It will come to this point.

12:35That's why you have to ask what is the value above 28.

12:38If the triangle with the base 32 and maximum height is the same,

12:44fix the base 32 here and when it comes to maximum height,

12:47it will come to 3.

12:48Now it's maximum.

12:49If there is no maximum value, you have to take that value and cut it.

12:53That's how you have to do it.

12:54What do you have to do to see if you get that triangle?

12:57Draw a parallel line.

12:59I drew a parallel line here.

13:01Then draw perpendicular lines.

13:04Perpendicular line from 1 and 2.

13:13Then perpendicular line from 3.

13:18Section point 3.

13:20Then take the compensated distance.

13:23Take the compensated distance from 1 to the x-axis.

13:29Mark it in the perpendicular line from 1.

13:31You will get point 1 in the true shape.

13:35Then take the compensated distance from 2.

13:40Mark it.

13:41You will get point 2.

13:44Then take the compensated distance from x-axis to 3.

13:48Mark it in the perpendicular line from 3.

13:50You will get the third point.

13:53These three are the points of the true shape.

13:56This one is 1, this is 2, and this is 3.

13:59Connect these three points.

14:03You will get the true shape triangle with base 32.

14:11This is 32.

14:12If you measure the distance,

14:14the height will be 50.

14:17Because we have taken 50.

14:20You will get the true shape according to the source.

14:25This is 50.

14:26This is 50.

14:27Is it clear?

14:28You have to do the dimensions and other things.

14:31This is the second question.
