A load of 21.7 kN is applied on a square and hollow strut with a gross cross-sectional area of 1,364 mm2. The maximum permissible compressive strength of the strut is 132 MPa, and the maximum permissible compressive bending stresses are 217 MPa. If there is no load eccentricity (offset) in the y-direction, calculate the maximum possible eccentricity in the x-direction that will satisfy the interaction "unity" equation. For the purpose of this question, the amplification of bending stress can be disregarded
