A large cement kiln has a length of 320 ft and a diameter of 15 ft. Determine the change in length and diameter of the structural steel [αS = 6.4 × 10–6/°F] shell caused by an increase in temperature of 320°F.

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.
