Conditions of the Tripod Limiting Equilibrium on a Horizontal Plane with Friction
2025, Vol. 21, no. 3, pp. 279-285
Abstract
The problem of limiting equilibrium of a heavy rigid body resting with three points on
a horizontal plane with Coulomb friction (tripod) is considered. The body can be brought out
of the state of limiting equilibrium by the shift torque of a couple of active forces lying in the
support plane, i. e., by the torque whose value does not disturb the equilibrium of the body but,
when the torque takes a greater value, equilibrium is broken. The maximum value of the torque
of friction forces in the supports, counteracting the shift torque, is found.
