The sum of these two forces can be found using a vector diagram. The two forces are represented ... The resultant force is represented in size and direction by the diagonal of the parallelogram.

These diagrams are curves in which the radius vector represents in magnitude and direction the resultant of the disturbing forces to which we may attribute the diurnal variation of the horizontal ...

Vector diagrams can be used to resolve the pulling ... vertical line between ends of the two lines arrow heads to show the direction in which each force acts Measure the lengths of the horizontal ...
