A horizontal bracket ABC consists of two perpendicular arms AB of a length 0.75 m and BC of a length 0.5 m. The bracket has a solid, circular cross 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 kNm in the x direction and M₂ = 1.0 kNm acts in the 2z direction. Considering only the moments M₁ and M₂, calculate the maximum tensile stress st, the maximum compressive stress s c, and the maximum in-plane shear stress t max at point p, which is located t super port A on the side of the bracket at mid-height.
