Assume that the thermal conductivity of copper is four times that of brass. Two metalrods made of copper and brass are each 20 cm long and 2.0 cm in diameter. The rods are placed end to end. The free end of the copper rod is maintained at 1000C and the free end of the brass rod is maintained at 00C.(i)What is the equilibrium temperature at the copper-brass junction

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.
