- X_[nu] = X_x cos(x, [nu]) + X_y cos(y, [nu]) + X_z cos(z, [nu]), (1)
- Y_z = Z_y, Z_x = X_z, X_y = Y_x. (2)
- When this quantity is negative there is "compression."
- Analytically, a strain is irrotational if the three quantities
- X_x cos(x, [nu]) + X_y cos(y, [nu]) + Z_x cos(z, [nu]) = X`_[nu], (2)
- P = - W(l - x)y/[pi]r^3t
