the surface of the water in the rotating tank is perpendicular to the effective gravitational force. the surface force on the mass element due to the rest of the fluid is perpendicular to the surface. the fluid is in static equilibrium in the rotating frame: (part a) use newton's second law in the rotating frame to find an equation for , the angle of the water's surface from the horizontal.

Answer :

Angular momentum and effective gravitational force about the mass center. For a rigid body rotating on a fixed axis with respect to its center of mass.

How does effective gravity become calculated?

The gravitational acceleration g = F / m can also be used to express gravity. Since the acceleration is constant for all masses m, m need not be included in the expression when using the gravitational acceleration instead of the gravitational force.

In fluid mechanics, what does g Effective mean?

It should be noted that a brand-new "effective gravity" vector, G, has been established as the vector sum of gravity and the opposite of the acceleration vector. With a little trigonometry, we can calculate the new effective gravity vector, which is the resultant vector of adding g and -a.
