Example 5. A steel stud (S( S = 8.27 x 10 10 Pa) 1 cm in diameter projects 4 cm from the wall. A 36,000 N shearing force is applied to the end. What is the defection d of the stud?

Volume Elasticity Not all deformations are linear. Sometimes an applied stress F/A results in a decrease of volume. . In such cases, there is a bulk modulus B of elasticity. Volume stress F A B Volume strain V V The bulk modulus is is negative because of of decrease in in V.
