A solid circular rod of diameter $d$ undergoes a bending moment $M=1,400lbf-$in inducing a stress $=\frac{32M}{d^3}.$ Using a material

strength of $25$ kpsi and a design factor of $2\mathrm{.}5,$ determine the minimum diameter of the rod. Using Table A$-17$ select a preferred

fractional diameter and determine the resulting factor of safety.

Minimum diameter of the rod is

in$.($Round the final answer to three decimal places.$)$

Preferred fractional diameter is $($Click to select$)vv$

The resulting factor of safety is

$($Round the final answer tor three decimal places.$)$
