Mechanics of materials is principally concerned with the determination of the stresses and deformation of engineering devices and structures. Stresses are important because, in combination with fundamental tests on engineering materials, they enable us to determine the loading conditions under which material failure will occur. Deformations may also be important insofar as they affect the kinematic function of a device.
