EXAMPLE 2.5.2. LEAST DIAMETER TO COUNTER DEFORMATION
A 2.5m long steel rod must not stretch more than 1.2mm when a 9kN load is applied to it. Knowing that E=200 GPa, determine the following:
The smallest diameter which should be used
The corresponding stress due to the load
With the given allowed deformation, we can draw out the diameter of the rod from its area:
The stress uses the same formula:
