Tilting moment (mechanics)
The mechanical overturning moment is a torque which , when exceeded, causes a body to overturn. It acts around the tilting axis, a body edge in the standing surface of the body, around which tilting occurs when the critical torque is reached.
The term is also used as a variable where the critical "overturning" overturning moment is merely the upper limit.
The tilt angle is the inclination of the surface on which a body subject only to the force of weight can stand so as not to tip over yet (there is an unstable equilibrium ). In general, the tilt angle is formed by the vertical and the straight line between the body's center of gravity and the next point on the tilting edge.
A road vehicle can e.g. B. tip over when driving transversely on a slope inclined by its tilt angle. At this moment, the vector of its weight runs between the vehicle's center of gravity and the tipping edge (straight line between the contact areas of the lower wheels). When cornering on a horizontal road, the vehicle can tip over if the resultant of the weight and centrifugal force hits the tipping edge (see also tipping limit ).
