The bracket shown in the figure has the same circular cross-section along the entire length. External force is 200 kN and it acts in y-direction. Shear failure stress is 80 MPa. The factor of safety is 2. Hint: This is not a bending problem, but a simple shear problem (at point A). Write the final solution in the box for this question. (a) What is the amplitude of the force reaction at the support A? (b) What is the allowable shear stress? 0.5 m 0.5 m AZ A F wall in MPa. in KN
