In this case, a moment is imposed in a single point of the beam, anywhere across the beam span. Taking moments about the section gives (obviously to the left of the section) M x = -P.x (negative sign means that the moment on the left hand side of the portion is in the anticlockwise direction and is therefore taken as negative according to the sign convention) so that the maximum bending moment occurs at the fixed end i.e. Moments of inertia can be found by summing or integrating over every 'piece of mass' that makes up an object, multiplied by the square of the distance of each 'piece of mass' to the axis. In practical terms, it could be a force couple, or a member in torsion, connected out of plane and perpendicular to the beam, as illustrated in the following figure. 15. beam fixed at both ends-uniformly distributed loads 16. beam fixed at both ends-concentrated load at center.
