The system of the collinear and the parallel force for the calculations of the equations in the determination of the fluid pressure are simplified as ________________$

• A. The simplified collinear force system gives us a net force and the parallel force system gives us a simplified force, and then we add it vectorially
• B. Such simplification is not possible
• C. The simplification is usually done by not considering the directions of the both
• D. The simplification is done by considering the rotations only
