Please solve as soon as possible would like to know how to solve this type of problem.

The bar below is subjected to an axial force of $70$ kN and a bending moment about the axis parallel to the hole of $100$ N$-$m$.$ Given the following dimensions, determine where brittle failure may occur and pick a high strength tempered steel for the material. r $=6$ mm$,$ d$=10$ mm$,$ h $=12$ mm$,$ w$1=90$ mm anProcess:

$1.$ Make some educated guess on likely location$/$locations for maximum stress

Will fail at either section A or where we have a fillet.d w$2=70$ mm$.$

$1.$ Compute stress

$2.$ Assuming Brittle failure, determine stress concentration factors

$3.$ Find principle stress $($including stress factors$)$

$4.$ Select material such that a reasonable factor of safety is achieved

$1)$ Calculate $+$ Apply stress per load type

$2)$ Define principle stresses

Apply BCM
