How do you find the Moment of a force about a point?
This is part 2 of a series on how you can go about finding the moment of a force about a point, you can watch part 1 here.
Determining the Moment of a force about a point can get a bit tricky, especially when the geometries we are dealing with get more and more complex.
But, come exam day, these problems don’t need to be a stumbling point.
In fact, after running through the process just once, you will see just how simple they can be.
You’ve got to know this…
The FE Exam is designed to challenge us to our limits.
And in doing so, it’s an exam testing how we perform under pressure just as much as it is one testing how well we grasp the fundamentals of engineering.
Much of the battle during this exam is making sure we stay calm and stable so that we can score our best.
This can only happen if you are putting yourself in difficult situations during practice.
We at Prepineer have designed our program to build our students up just as they do athletes leading up to a competition.
We will challenge and stretch you at all levels so that no matter what you see, you are prepared.
In this video, we dive into a FE Exam Practice Problem, this time within the subject of STATICS, specifically revolving around finding the MOMENT of a FORCE about a POINT.
This is PART 2 of 2 for this particular problem.
You can watch part 1 where we took the first steps in determining the Moment generated about a point.
Key Definition
What is a MOMENT?
A MOMENT quantifies a force’s tendency to cause a body to rotate about a specific point or axis.
This is different from the tendency for a body to move, or translate, in the direction a force is acting.
In order for a moment to develop, the force must act upon the body in a way that causes it to begin to twist.
This occurs every time a force is applied so that it does not pass through the centroid of the body.
A MOMENT is due to a force not having an equal and opposite force directly along its line of action.
So how can you go about determining the moment of a force about a point?
Check out the video and see how we can go about solving this type of problem in the most efficient manner.
As always, with Love, Prepineer
