The moment of inertia is graphically determined by ___________ with the help of space diagrams, polar diagram, force diagram and funicular polygons.(a) culmann’s method(b) calibration method(c) continuity method(d) coloumb methodI had been asked this question in examination.My enquiry is from Centres of Gravity and Moments of Inertia of Area topic in division Development of Surfaces, Isometric Projections, Perspective Projections & Transformation of Projections of Civil Engineering Drawing

Answer»

The correct choice is (a) culmann’s method

For EXPLANATION I would SAY: BASED on the sliding plane hypothesis of Coulumb earth pressure theory, a new method for calculation of the passive earth pressure of cohesive soil was constructed with Culmann’s graphical construction. The influences of the cohesive FORCE, adhesive force, and the fill surface form were considered in this method.
