Question

The tensile stress adjacent to hole will be ____________

(a) about five times the average stress on the net area

(b) about half the average stress on the net area

(c) equal to average stress on the net area

(d) about two to three times the average stress on the net area

I got this question during an online exam.

The origin of the question is Modes of Failure, Slenderness Ratio and displacement topic in section Design of Tension Members of Design of Steel Structures

Answer 1

Correct choice is (d) about two to three times the average stress on the net area

The best explanation: From the theory of elasticity, the tensile stress adjacent to hole will be about two to three times the average stress on the net area, depending upon the ratio of diameter of hole to the width of plate normal to direction of stress.
