Flexural rigidity is defined as the force couple required to bend a non-rigid structure to a unit curvature or it can be defined as the resistance offered by a structure while undergoing bending. ==Flexural rigidity of a bar== (詳細は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 second moment of area (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). 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Flexural rigidity」の詳細全文を読む スポンサード リンク
