Wired Faculty App

A beam has one end fixed in a wall and loaded at the other end. Three locations A, B and C are shown in figure. Which location would you prefer to make a circular hole?

Solution

At point A, the beam undergoes tensile strain, therefore hole at A will increase in size along the length of the beam and becomes oblate. 

At point C, the beam undergoes compression strain, therefore hole at C will decrease in size along the length of beam and becomes prolate. 

The point B is in neutral zone, therefore the hole at B will be circular.
