Basic Stress and Strain,Direct stress is the internal force a material exerts per unit of its area . when it resists an external axial force, W. Since the external force may be either tensile (+) or compressive (?) the direct stress is written as:

Elasticity,Elastic moduli for tension and shear were defined in Chapter 3 as . = . and . = . respectively. . is commonly called . and . the .. Two further elastic constants can be defined for materials operating under elastic systems of stress: . and the ..

stress-test

Bending and Shear,The engineer’s theory of bending (ETB) enables the longitudinal bending stress ., to be found anywhere in the cross-section of an initially straight beam when the bending moment ., at that section is known. Let the radius of curvature ., in Fig. 5.la define the untrained longitudinal fibre OO, which will be referred to as the neutral axis (NA).

Not only is the choice of material important to this goal but also the correct analysis of the manner in which the external loads are supported. It is via this route that a safety factor is decided upon, given other constraints such as weight, stiffne
