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
Young's modulus is the ratio of stress (which has units of pressure) to strain (which is dimensionless), and so Young's modulus has units of pressure.Its SI unit is therefore the pascal (Pa or N /m 2 or m â1 Â·kgÂ·s â2). The practical units used are megapascals (MPa or N /mm 2) or gigapascals (GPa or kN/mm 2).oung's modulus is the ratio of stress (which has units of pressure) to strain (which is dimensionless), and so Young's modulus has units of pressure.
