Are resultant force and total force the same?

Click For Summary
SUMMARY

The discussion clarifies that resultant force and total force are not the same in the context of fluid mechanics. Resultant force refers to the average force acting on a surface, while total force accounts for the cumulative effect of pressure over the entire area. The wall in question is 20 ft long, and the calculation of total force due to water pressure requires understanding these distinctions. Additionally, the importance of providing accessible visual aids for problem-solving is emphasized.

PREREQUISITES
  • Understanding of fluid mechanics principles
  • Knowledge of pressure distribution in fluids
  • Familiarity with calculating forces on submerged surfaces
  • Basic skills in using image-sharing platforms for problem illustrations
NEXT STEPS
  • Study the differences between resultant force and total force in fluid mechanics
  • Learn how to calculate total force on submerged surfaces using hydrostatic pressure equations
  • Explore methods for locating the center of pressure on vertical surfaces
  • Review best practices for sharing visual aids in online discussions
USEFUL FOR

Students studying fluid mechanics, civil engineers involved in structural design, and educators teaching principles of hydrostatics will benefit from this discussion.

Homework Statement


The wall shown in Fig. 4.28 is 20 ft long. Calculate the
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.
