The bracket has a solid, circularcross section with a diameter equal to 65 mm. The bracket is inserted in a frictionless sleeve at A (which is slightly larger in diameter), so it is free to rotate about the z0 axis at A and is supported by a pin at C.Moments are applied at point C M1 = 1.5 kN m in the x direction and M2 = 1.0 kN. m acts in the -z direction.Considering only the moments M1 and M2, calculate the maximum tensile stress σv, the maximum compressive stress σc, and the maximum in-planeshear stress τmax at point p, which is located at support port A on the side of the bracket at mid-height.arrow_forward
