Human Figures in Action. In portraying figures in action, the principles of equilibrium may portray various forms of action other than falling, but a figure out of balance conveys to the eye the impression of falling. Thus:

In the upper drawing the figures have no ''visible means of support." In the lower part the deficiency is supplied.
As a general rule, if a vertical line is drawn from the feet upward, and half of the figure lies on each side of the line, the figure will appear balanced.
