What is a Moment? The Moment of a force is a measure of its 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 of the force. In order for a moment to develop, the force must act upon the body in such a manner that the body would 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 it's line of action.

Imagine two people pushing on a door at the doorknob from opposite sides. If both of them are pushing with an equal force then there is a state of equilibrium. If one of them would suddenly jump back from the door, the push of the other person would no longer have any opposition and the door would swing away. The person who was still pushing on the door created a moment. Elements of a Moment. The magnitude of the moment of a force acting about a point or axis is directly proportinoal to the distance of the force from the point or axis.
It is defined as the product of the force F and the moment arm d. The moment arm or lever arm is the perpendicular distance between the line of action of the force and the center of moments.
The Center of Moments may be the actual point about which the force causes rotation. It may also be a reference point or axis about which the force may be considered as causing rotation.
It does not matter as long as a specific point is always taken as the reference point. The latter case is much more common situation in structural design problems. Harry Potter and the Order of the Phoenix.
The Weasleys all clearly skipped Muggle Studies, and the Dursleys definitely have a no-wizards-welcome policy. So those times their worlds collided are some of our favourite funny moments. With a plug? Gracious, I must see that ….

The Humanities Moments Project was created to collect personal stories about encounters with the humanities. The stories on this site are presented as submitted, capturing the experiences of those who've shared them in their own words — reflecting their individual views, interpretations, and conclusions.
