Afull journal bearing is required for a shaft with the following specifications: nominal diameter 40 mm diametric clearance 60 µm rotational speed (rpm) 1450 load on the bearing 2100 n inlet temperature of the lubricant 60°c bearing length to diameter 1. assume the lubricant is sae 10 and an initial temperature change is 15°c. a)-determine the overall temperature rise in the bearing. b)-determine the flow rate of the lubricant required.

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.
