Unformatted text preview: (b) If the column has a 0.40 m x 0.40 m square cross-section, what is the probability P F that it fails i.e. ] f [ P P c F > = ? Assume W and f c are independent. Hint: c f ln 1 c f c f < < < (c) Determine the required cross-sectional area of the column for a target failure probability of 10-3 . (d) Find the mean stress A m m W = as a function of the failure probability P F . Plot against for between 10 ) P ( m F ) P log( F F P-4 and 10-1 ....
