When the point of application of either force lies in anyother angle than YOX, to its co-ordinates must be given theirappropriate sign.

The general formulae (a), (b), (c) will apply to all cases,by giving the proper signs to the forces and to the co-ordinatesof their points of application. These formulae are more…
