Mechanics and heat were covered in previous chapters. This chapter shall cover the effects of mechanical and thermal loads on the geometry of bodies.
The nature of a mechanical load affects the nature of the deformation of a body. Uniaxial forces cause simple extension or compression of a specimen. Two opposite, non-collinear forces cause shear, where cross-sections slip past each other. A clockwise force acting in conjunction with an anticlockwise force causes a beam to bend if they act in a plane running along its length, but produces torsion (twisting) if they act on parallel cross-sections.
All these cases are covered in this chapter.
