Q: The moment-area method uses ........... diagram.
  • A. difference of the area of moment and flexural rigidity
  • B. the area of moment multiplied by the flexural rigidity
  • C. summation of the area of moment and flexural rigidity
  • D. the area of moment divided by the flexural rigidity
Correct Answer: Option D - Moment area method is also known as Mohr's method. • In this method establishes a procedure that utilizes the area of the moment diagrams (actually, M/EI diagram) to evaluate the slope or deflection at selected points along the axis of a beam. • This method is applicable to both beams and frames. In this method continuity of slope is assumed. • This method is not applicable where there is a sudden break in the continuity of slope such as an internal hinge or internal links are present.
