A full journal bearing has a journal diameter D of 25 mm, with a unilateral tolerance of –0.038mm. The bushing bore has a diameter B of 25.038 mm and a unilateral tolerance of 0075mm .The l/D ratio is unity . The load is 1.1kN and the journal runs at 18.33 rps. The minimum film thickness variable is 0.58 and coefficient of friction variable is 4.0
Find
(a) sommerfeld number
(b) minimum film thickness
(c) frictional torque
