A graded steel cylinder AISI 1030 is connected to a wall and loaded with axial forces.
F = 30 [kN]
d1 = 35mm
d2 = 20mm
Elastic Model: E = 2x105 MPa
Safely coeffecient: 2
Yield strength limit: 440 MPa
1) Describe the course of the internal forces along the beam and the course of the efforts.
2) Check beam for strength
3) Calculate the total distortion of the beam
The Attempt at a Solution
Since I don't see a 3D drawing or references should I treat this problem like a 2D problem?
1) I presume they're asking for a free body diagram here:
If I treat it like 2D:
Before I can use the formula: Sigma = F/A
I need to find A. So,
A = 1 x 0.020 + 2 x 0.035 = 0.09m2
sigma = F/A
sigma = 30+30(2.5)/0.09
sigma = 1166 N/mm2

Is that correct?
