WebTorsional shear stress is the shear stress offered by the body against torsional load or twisting load. it is denoted by the symbol ‘𝜏’. The value of torsional shear stress varies within the cross-section of the object. The value for shear stress is minimum at the neutral axis of the cross-section while it is maximum at the outermost ... Weby-direction, and T is the shearing stress. For laminar shear flow, q = -kdT/dy and T = J.Ldu/dy, and one sees that the expression (1) above holds if, and only if, the Prandtl Number IJ i8 unity. Hence the Reynolds analogy is strictly correct for laminar shear flow pro vided the fluid properties are such that IJ = 1. The * Robert H. Goddard ...
