xy X Om and is negative. The sum of the momentsof T, P,, and P^ about a point x, is not given by a singleordinate rnultiplied by Om, since the force P^ does notcome next in the construction. The sum of the momentsof T and P^ about x, = x/y^ x Om, and the moment ofP, = zz X Om ; hence, these moments… … Fig. 41. 26 Modern framed structures. Application. 45. First.
