total force on the wall due to water pressure and locate the
center of pressure

Homework Equations


Are resultant force and total force the same?

The Attempt at a Solution


I think they are not the same because resultant force is the same as average force right?

What are your relevant equations? Right now you've put a question in the relevant equations section. A question is not a relevant equation. Questions belong in the problem statement, or sometimes in the attempt at a solution if you reach a point where you question a step you've attempted or need a clarification on a step.

What is the difference between resultant force and total force?

Resultant force and total force are often used interchangeably, but there is a subtle difference between the two. Total force is the sum of all forces acting on an object, whereas resultant force is the single force that has the same effect as all the other forces combined.

Is resultant force always equal to total force?

No, resultant force is not always equal to total force. If the forces acting on an object are balanced, meaning they cancel each other out, the resultant force will be zero even though the total force is not.

How can I calculate resultant force?

To calculate resultant force, you need to know the magnitude and direction of each individual force acting on an object. You can then use vector addition or trigonometry to determine the resultant force.

Can resultant force and total force ever be in opposite directions?

Yes, it is possible for resultant force and total force to be in opposite directions. This occurs when the forces acting on an object are unbalanced, meaning there is a net force in one direction and a resultant force in the opposite direction.

Why is it important to understand the difference between resultant force and total force?

Understanding the difference between resultant force and total force is crucial in analyzing the motion and stability of objects. It allows scientists to accurately predict the behavior of objects and make informed decisions in various fields such as engineering, physics, and mechanics.
