Machine Elements<br/><br/><br/>As shown in Figure 2, when the steel

pipe piece with a diameter of 40mm outside hole is 40mm, hole diameter of 20mm, hole diameter of 40mm is pressed tightly with a pressed steel pipe part, the maximum coefficient of stress coefficient according to the maximum shear stress theorem that occurs due to the radial σr and tangent σt stresses in the aluminum pipe. What should be the outer diameter of the steel pipe to be 3? Tensile, shear strength of aluminum material is given as Sut = 250MPa, Sy = 200MPa, Elastic modulus E = 70GPa, Poisson ratio υ = 0.29, Sy = 500MPa of steel pipe, Sut = 600MPa, and E = 210GPa, Poisson ratio υ = 0.33. During the tight fit in calculations, the effects of friction occurring on the outer surface of the steel pipe and the hole surface of the aluminum pipe will be canceled.
