Question

If solving the question in 3D calculations is difficult, then use the 2D system to determine the equations of the fluid pressure.

(a) True

(b) False

I have been asked this question during an interview for a job.

This intriguing question comes from Fluid Pressure topic in chapter Centre of Gravity and Centroid of Engineering Mechanics

Answer 1

Correct option is (a) True

For explanation I would say: The answer is obviously yes. If we are having any difficulty in making the vector components, then we can go in 2D. As if the particle is in equilibrium, the net force will be zero. No matter where you see first. Net force is zero.
