[mechanics] Why can moment vectors be freely moved?
In statics, moments – or couples – are treated as “free vectors” which means that they can move freely unless the direction of application is changed. It implies that the point of application of moment is meaningless while that of force is not. Therefore, the beams shown below are exactly under the same condition as a point of view of statics. (But not of mechanics of materials! It should be car..
