The cylindrical bar in the figure has a total length L=1.2 m, a diameter d=15 mm, and is confined by fixed supports at the walls A and B. A concentrated axial load FC=30 kN is applied to the bar at point C as indicated in the figure, with LACLBC. The bar is homogenous with Young’s modulus E. The material will fail if the magnitude of axial stress in the material exceeds σf=226 MPa.

Question

The cylindrical bar in the figure has a total length L=1.2 m, a diameter d=15 mm, and is confined by fixed supports at the walls A and B. A concentrated axial load FC=30 kN is applied to the bar at point C as indicated in the figure, with LAC>LBC. The bar is homogenous with Young’s modulus E. The material will fail if the magnitude of axial stress in the material exceeds σf=226 MPa.

I do not see a question here. Whether or not the bar fails will depend upon where the axial load is placed.
