what is the relation between angle twist and shear angle referring TORSION ps in geometric terms
|dw:1345033703457:dw| gamma is shear angle n theta is angle of twist assume length l , radius r
angular displacement bb' = \[2 (\pi / \theta) r\] (for circle) anglular dispalcement= \[2 (\pi / \alpha) l\] for lenght if both distance are equal then put both equal we get \[(\pi / \theta) r = (\pi/\alpha) l\] \[r/ \theta =l/ \alpha\]
