Flexural Rigidity of A BAR
In a beam or rod, flexural rigidity (defined as EI) varies along the length as a function of x shown in the following equation:
where is the Young's modulus (in Pa), is the 2nd moment of inertia (in m4), is the transverse displacement of the beam at x, and is the bending moment at x.
Flexural rigidity has SI units of Pa·m4 (which also equals N·m²).

Famous quotes containing the words rigidity and/or bar:
“[University students] hated the hypocrisy of adult society, the rigidity of its political institutions, the impersonality of its bureaucracies. They sought to create a society that places human values before materialistic ones, that has a little less head and a little more heart, that is dominated by self-interest and loves its neighbor more. And they were persuaded that group protest of a militant nature would advance those goals.”
—Muriel Beadle (b. 1915)
“Even the most incompetent English actor, coming on the stage briefly to announce the presence below of Lord and Lady Ditherege, gives forth a sound so soft and dulcet as almost to be a bar of music. But sometimes that is all there is. The words are lost in the graceful sweep of the notes.”
—Robert Benchley (1889–1945)
