Capital Project Word of the Week - Civil/Structural Engineering
Thank you for visiting our Capital Project Word of the Week website feature. Our theme this month is Civil/Structural Engineering. We hope this provides you with some meaningful information about our industry and the services we provide. Each week we will be adding a new Word of the Week to the page. Come back frequently to see our new additions!

Moment is the measure of force that causes an item to want to rotate about a specific point or axis and is a term regularly used in the field of structural engineering. The magnitude of the moment is affected by two variables, “Force” and “Moment Arm”. To calculate the magnitude of a moment, you multiply a “Force” times its “Moment Arm”. In industrial designs, these types of forces are seen in almost every design. Moments need to be accounted for to assure we have designed and erected a safe structural system.
Moment = Force x Distance or M = (F)(d)
Example calculation: Pushing on a 2ft long wrench with 10lbs of force to turn a nut.
The Moment calculation for this example is shown below. Forthis example, you would say you are applying 20 foot-pounds of moment on thenut.
- Moment = Force x Moment Arm
- Moment = 10lbs x 2ft
- Moment = 20 ft-lbs
