Arail maintenance team is studying the downtime of the 9e locomotive. data analysis in thousands of rands for a 4 month period is: back pressure regulator, 30; adjust feed worn, 15; jam copper head, 6; lost cooling, 52; valve replacement, 8; and other 5. a) construct a pareto diagram for one month. b) identify the vital few and important many for that particular month.

On a average work day more than work place firs are reorted

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
