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
Now we will apply a special formula from the text book, which is: v = (Ft/(m/l))1/2. or v = T/. Where  = mass/length for the cord, and T is the tension in the cord. have: T = 150N; m = 0.55kg; and l = 30m, so  = (.55 kg)/(30 m) = 0.01833 kg/m. Therefore, v = T/ = (150 N/(0.01833 kg/m)) = 90.45m/s.
