IT ØD VP The figure (not drawn to scale) shows a metallic cylindrical column submitted to a combined load: bending and torsion. The column contains an hemispherical groove of radius r, located at a distance L from the point of application of the loads. T, You are given the column diameter D=68 mm, the groove radius r=6 mm, the distance L = 200 mm, the bending load P=5 kN, and the torque T = 600 N.m. The material data are Young's modulus E=122 GPa Shear Modulus G = 55 GPa Poisson's ratio v=0.1 and Yield strength dy = 380 MPa. a) Write a numbered list of the calculation steps required to obtain the factor of safety in yielding based on the maximum distortion energy (Von Mises) criterion. Enter your answer in the box below

b) Calculate the factor of safety in yielding based on the maximum energy (Von Mises) criterion. The answer is acceptable within a tolerance of .1 Answers out of this +/-0.1 tolerance, but within a 10% tolerance will score 8 marks Note that the F.O.S can be lower than 1 in this question. F.O.S.: (15 mark)
