WHY STUDYMechanical Properties?
It is incumbent on engineers to understand how the
various mechanical properties are measured and what
these properties represent; they may be called upon to
design structures/components using predetermined
materials such that unacceptable levels of deformation
and/or failure will not occur. We demonstrate this
procedure with respect to the design of a tensile-testing
apparatus in Design Example 7.1.
