Statics: Couples - Engineering Statics
A couple consists of two parallel forces, equal in magnitude, opposite in direction, and non-coincident. Couples are special because the pair of forces always cancel each other, which means that a couple produces a rotational effect but never translation.
Reduce a force and a couple at a given point to a single force. The single force is obtained by moving the force until its moment about the point (A) is equal to the couple vector MA. R A position vector r from the point, to any point on the line …

2024年10月18日 · Resolve the applied couple M into components parallel and perpendicular to the neutral axis using the angle β. Calculate the bending stress using the formula: σ= I M y ⋅y + I M z ⋅z where M y and M z are the components of the moment, and y and z are the distances from the neutral axis to the points.
