A displacement vector u is described by its three components «( in spacial co-ordinates x,, as

Detennine the components of infinitesimal strain and rotation matrices, «j and a^, for a point P(0,1,2), whenfcj = J^= 1 and&3 = 2. What men is me change in the right angle between a pair of perpendicular lines passing through P with direction cosines: (1A/3,1/^3, - 1//3) and (W14,2/^14,3A/14) with respect to X₁, X₂
and X₃
JCJ?
