Question: Choose an Oiles SP 500 alloy brass bushing to give a maximum wear of 0.002 in for 1000 h of use with a 400 rev/min

Choose an Oiles SP 500 alloy brass bushing to give a maximum wear of 0.002 in for 1000 h of use with a 400 rev/min journal and 100 lbf radial load. Use hCR = 2.7 Btu/ (h. ft2. ◦F), Tmax = 300◦F, fs = 0.03, and a design factor nd = 2. Table 12–13 lists the bushing sizes available from the manufacturer
