Q$\mathrm{.}2.$ A $25-$mm long full journal bearing having diameter of $50$ mm runs at $600$ rpm$,$ and has a radial clearance of $0\mathrm{.}02$ cm$.$ The SAE $40$ oil supply is used and coefficient of friction of the bearing is $0\mathrm{.}005.$ Note that the shaft is not concentric with its bushing. When the bearing supports $5000$ N$,$ find the following: a$.$ Unit load, P b$.$ Bearing characteristics number, S c$.$ Oil viscosity, $$ d$.$ Average operating temperature, Tav e$.$ Temperature rise of the oil, $$T f$.$ Inlet temperature, T$1$ g$.$ Heat generated, H h$.$ Eccentricity ratio, i$.$ Minimum film thickness, h$0$ j$.$ Minimum film thickness position, k$.$ Total amount of oil volume flow rate, Q l$.$ Side leakage, Qs$.$ Figure $12-3$
