How useful is Bernoulli's equation? How restrictive are the assumptions governing ... top surface is less than the average pressure over the bottom surface, and a resultant force due to this pressure ...

then the resultant forces acting at these two points must be collinear in order for the body to be in equilibrium. This result is readily proved by using the equations of equilibrium for the body.

So grab your pen, grab your paper. Let's write this down. ELLIE: The equation to calculate resultant force is: resultant force equals mass, multiplied by acceleration, which is written as ...
