Designing in AutoCAD

Offering remote work. You need to design the pipe in the autocode, set the material for it, make loads :

1. Internal gas pressure

2. External pressure of the soil from above (the pipe lies in the trench from above presses the soil)

Describe the schedules of these stresses

Background:

Diameter 1220 mm

Wall thickness 12 mm

Pipe length 10 m

Temporary resistance to break 550 MPa

The yield limit is 410 MPa

12G2SB steel

5 photos: this is a section of the track, here the first and second layer of soil, at the bottom of the number, this is the depth of the trench, which is dug directly under the pipe.

2 days maximum. I'm willing to pay a lot.
