In this article the authors discuss how the research paradigm and methodology work together to form a research study. The qualitative, quantitative and mixed methods debate is then discussed as it pertains to the decisions that need to be made by the researcher.t is, therefore, a priority of this article to 'demystify' the role of paradigms in research. The article then moves to a discussion of methodology as it relates to the research paradigm.
The classic formula for determining the bending stress in a beam under simple bending is: = where. is the bending stress â the moment about the neutral axis â the perpendicular distance to the neutral axis
A shear stress, denoted Ï (Greek: tau), is defined as the component of stress coplanar with a material cross section. Shear stress arises from the force vector component parallel to the cross section. Normal stress, on the other hand, arises from the force vector component perpendicular to the material cross section on which it acts.
