Webor uniform torsion. It is used in calculating the buckling moment resistance of laterally unsupported beams and torsional-flexural buckling of compression members in accordance with CSA Standard S16.1-94 (CSA 1994). For open cross sections, the general formula is given by Galambos (1968): ∑ ′ = 3 b t3 J [1] WebTorsion of a G-structure. Associated to any G-structure is a notion of torsion, related to the torsion of a connection. Note that a given G-structure may admit many different compatible connections which in turn can have different torsions, but in spite of this it is possible to give an independent notion of torsion of the G-structure as follows.

Indeed, if x T is torsion in G / T, then e T = ( x T) m = x m T for some m > 0. This means x m ∈ T, so ( x m) n = e for some n > 0. Therefore x m n = e and x ∈ T, so x T = e T and there is no nontrivial torsion element in T. derbyshire county council job sheet
