A .05 wide journal bearing supporting the loads on a 1 inchshaft just meets the Trumpler’s design criteria for a FACTOR OFSAFTY OF 2.05. The bearing satisfies all the other Trumpler’sdesign criteria by much larger margin. Your colleague suggests thatincreasing the bushing width to 0.75 inches would be an adequatedesign and you would not need to conduct another journal bearinganalysis because the greater width would result in a bearing whichsatisfy all of Trumpler’s design criteria.
Do you agree with your colleague that you can state that the0.75 inch wide journal bearing would exceed Trumplers Designcriteria and that no additional analysis is required? Justify youranswer.
