Consider a solid round bar of radius r and length l. compute the total elastic energy in the bar when it is subjected to an axial end-load p. com- pute the total deviatoric energy in the bar. com- pute the total hydrostatic/volumetric energy in the bar. do your last two expressions add up to the first?

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.
