A 2.500-in-diameter round steel bar (E = 29 000 000 lb/in2 and μ = 0.303) slides tightly through a hole. When not under load, there is a clearance of 0.0001 in on all sides of the bar. A 125-kip compressive load is applied to the end of the bar.
(a) Estimate the cross-sectional dimension of the bar when under load.
(b) Minimum adequate clearance is 0.000 05 in on all sides. Does the bar still have adequate clearance when the load is applied to it?
