(tco 6) consider a demand-paging system in which a process is allocated six frames. let the least recently used (lru) algorithm be employed to select pages for replacement. let the sequence of page references for the process be as follows: 1, 3, 4, 1, 5, 2, 3, 8, 6, 7, 10, 3, 9, 4, 3, 8, 5, 1, 2, 5, 3, 1, 7, 5, 1, 2 at the end of processing the above sequence of references, determine the set of pages resident in memory. now, identify the page reference from the following that will cause a page fault.

A8-in.-diameter steel shaft is to have a press fit with a 16-in-diameter cast iron hub. both the hub and the shaft are 10 in long. using maximum normal stress theorem and appropriate safety factor, it was identified that the maximum allowable circumferential (a.k.a. hoop or tangential) stress in the hub is to be 7.5 ksi. the moduli of elasticity are 30 x 106 psi for steel and 15 x 106 psi for cast iron. the poisson's ratio for both steel and cast ron is 0.3 and coefficient friction for the two materials is 0.12. determine a. the interference or the original mismatch, 8 b. the maximum axial force required to press the hub on the shaft
