How to use in-sentence of “second moment”:
+ However, it must be noted that this does not have any bearing on the torsional rigidity provided to an object by its constituent materials; the polar second moment of area is simply rigidity provided to an object by its shape alone.
+ While the planar second moment of area is most often denoted by the letter, in engineering textbooks.
+ In the most simple form, the polar second moment of area is a summation of the two planar second moments of area,.
+ In essence, as the magnitude of the polar second moment of area increases i.e.
+ If instead of force, the area of the figure or mass of the body is considered, it is called the second moment of area or second moment of mass.
+ When applied to non-cylindrical beams or shafts, the calculations for the polar second moment of area becomes erroneous due to warping of the shaft/beam.
+ It is one aspect of the :en:Second_moment_of_areasecond moment of area linked through the perpendicular axis theorem where the planar second moment of area uses a beam’s cross-sectional shape to describe its resistance to plane parallel to its neutral axis, the polar second moment of area uses a beam’s cross-sectional shape to describe its resistance to deformation when a moment perpendicular to the beam’s neutral axis.
+ As shown, higher torques and beam lengths lead to higher angular deflections, where higher values for the polar second moment of area, reduces the potential for angular deflections.
