A shaft is composed of elements made of S355 with a modulus of elasticity of 2.1×1052.1×105 N/mm² and a Poisson's ratio of 0.3. As shown in the picture, on the right side, there are two forces of 10,000 N each, acting at an angle of 15° upwards, creating a moment that is statically compensated by the force F2​ on the left side. The shaft is supported at positions A and B. In the same position (for simplicity), there are two critical cross-sections leading to stress concentrations. The sleeve near F2​ is shrink-fitted. The dimensions there are d=50 mm, D=120 mm, and the length of the sleeve is 50 mm. Ha=1 µm and Hn=1 µm. The fit is H7/s6. Determine breell​.
