A five legged intersection has safety issues. in 2018, the number of crashes reported was 48 and the average 24 hour volume entering the iintersection was, going clockwise around the intersection - 980, 1560, 1230, 900 and 1435 vehicles Determine the crash rate per million vehicles.

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.
