A 'L' shaped post with a cylindrical cross-section is loaded with a concentrated load at its free end (as shown below). The lower support, point A, can be considered built in. The concentrated load, P, acts on a horizontal plane. The circular cross-section of the pole has an outer diameter of 115mm and an inner diameter of 110mm.

Transcribed Image Text:A 'L' shaped post with a cylindrical cross-section is loaded with a concentrated load at its free end (as
shown below). The lower support, point A, can be considered built in. The concentrated load, P, acts
on a horizontal plane. The circular cross-section of the pole has an outer diameter of 115mm and an
inner diameter of 110mm.

Determine state of stress at the remaining points (P2, P3 and P4). Calculate the maximum
principal (01) and maximum in-plane stress (Tmax) for the remaining points (P2, P3 and P4)
located at Point A. Present your results in a table and ensure that your sign convention is
clearly shown (and applied consistently!)
Hint: It may be useful to use Mohr's circle.
