is the suitable cross-sectional region for the quantity for which the pressure tensor is getting calculated. This formalism incorporates force conditions connected with forces that act standard into the cross-sectional location (the matrix diagonals of the tensor) in addition to shear terms affiliated with forces that act parallel into the cross-sectional space (the off-diagonal things).
The resultant force can be found by setting up a parallelogram with the Original force vectors forming two adjacent sides. The diagonal from the parallelogram offers the resultant force vector. (more)
