Though Simon followed all safety protocols, he was injured at work because a machine was not properly guarded. Even though there is no reasonable belief that drug use contributed to the employee’s injury, his employer required him to take a drug test after he reported the injury. Did the employer misuse a drug testing program against Simon for reporting an injury?

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.
