Hence the principal stresses can be found for 23 and so and p2 = _E__ (e2 1 - v2 + vel) It is also possible to find other direct and shear strains for the given point. Solution of equations (i), (ii) and (iii) can be tedious and if many results are to be analysed a small desk computer will be found useful. It will be appreciated that e1, e 2 , p 1 and p 2 are the strains and stresses at the surface of the material. Given eb 1 X 10- 4 3 X 10- 4 = ec with A. 6667 The signs are determined by the loading situation, for example, on a beam the rosette can be on the tensile or compressive side.

M and N can therefore only describe translatory movements of the whole body. Consequently M and N have no effect on the strain and can be eliminated from the displacement equation. 22b, B must be zero otherwise shearing would occur on radial planes due to the tangential displacement of a point given by (ra, e = 0, 2~, 4~, etc).

10c that a constant -Pa 2/2GI occurs. 10b). It is usual in such instances to let A+ B = -Pa2/2GI. This does not increase the constants of integration, which decide the boundary conditions because if A is known, B can be found.
