The value of stress concentration factor depends on the geometry. If Ka and Kb are stress concentration factor for case (a) and case (b), respectively, which answer of the following is true?
Ka > Kb
KA = KB
KA < KB
None of the rest.
Expert Solution
Step 1
Option a is correct here
stress concentration factor shall be high in the first question bcoz we know the smooth transition between two various sized diameter shaft connections lessens the stress concentration.
also from any stress concentration graph we will know
k is dependent on r/d hence in the second option r value is given in the form of a fillet
