Asteel machine part is statically loaded to 70 mpa and has a yield strength of 320 mpa. find the factor of safety being used in this situation. (b) due to buckling the failure load of a steel column in a building is estimated to be 10 kn. with a design factor of 5, calculate the allowable load for the steel column.

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.
