7 in. o.d., 6 in i.d, 16 in long) is used to A bronze coupling sleeve (nominal connect two solid steel shafts (each nominal 6 in o.d.) as shown below: bronze coupling sleeve 6 in 7 in steel shaft steel shaft 16 in afts turn at 1800 rpm, and The sleeve is not keyed, splined or pinned. The two sh 3000 ft-Ibf of torque are transmitted through an interference fit. The coefficient of static friction between the bronze coupling sleeve and the steel shafts is 0.16. The shafts operate in a 190 °F environment, but the coupling sleeve is press-fitted when sleeve and shafts are at 70 °F. Use the following data to determine what the initial (at 70 °F) interference should be: Prope Steel Bronze -6 Coeff. of Thermal Expansion 6.5x10 1/°F 10.2x10° 1/°F Young's Modulus Shear Modulus Poisson's ratio 2.9x107 psi 1.6x101 psi 1.1x10 psi 6.0x10 psi 0.30 0.33
