Step 1
The moment (or torque) about a point is the measure of the tendency of a force to rotate an object about that point. It is calculated as the product of the force and the perpendicular distance from the point to the line of action of the force. The formula for Show more…

A crate has four forces and a couple moment applied to it. Calculate the resultant force and moment about the origin. Then calculate a point on the crate at which the resultant force alone will produce the equivalent effect on the crate.

Determine the moment of each of the three forces about point A. Determine the moment of each of the three forces about point B. F1 = 250 N F2 = 300 N F3 = 500 N
Determine the resultant moment of the four forces acting on the rod shown in Fig 1 about point O.
