Aring of sae 301 stainless steel is to be placed on a shaft having a temperature of 20°c and a diam- eter of 55.200 mm. the inside diameter of the ring is 55.100 mm. to what temperature must the ring be heated to make it 55.300 mm in diameter and thus allow it to be slipped onto the shaft?

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
