stability coefficient, force of gravity, external force, overturning
This paper is a continuation of the earlier work, which considered the stable equilibrium of upright human body in the absence of external factors. External forces are introduced herein, which may disturb the stable equilibrium and cause the body to tumble. The paper also introduces the concept of the coefficient of the stable equilibrium and proposes a formula for its calculation. Finally, a formula is set up to obtain the maximum value of external forces under which the body still maintains the state of equilibrium.
