Their boundary conditions at the mid-arc of the arch can be defined by the deflections ( w , v ) and the bending moment M characterized in a symmetrical and anti-symmetrical manner.
WebAccording to , a relation R on a given set is symmetric if whenever x ′ R x ″, then x ″ R x ′. Still, according to , a relation R on a given set is antisymmetric if whenever x ′ R x ″ and x ″ R x ′, then x ′ = x ″. It follows that a relation R cannot be both symmetric and antisymmetric, unless R is restricted to the elements ... WebLet P = P (A) be the power set of A.
