There are Figure 1 presents a balanced system, such as the toy doll on the man’s hand, which has its center of gravity (cg) directly over the pivot, so that the torque of the total weight is zero. Stability is also increased if the base is expanded by placing the feet farther apart.Animals such as chickens have easier systems to control.

Other articles where Stability is discussed: motivation: Attribution theory: …falling along three dimensions: locus, stability, and controllability. (b) While bending in the manner shown, stability is increased by lowering the center of gravity. The body of the chicken is supported from above by the hips and acts as a pendulum between them.Engineers and architects strive to achieve extremely stable equilibriums for buildings and other systems that must withstand wind, earthquakes, and other forces that displace them from equilibrium.

Delivered to your inbox! The chicken is in stable equilibrium. The net external force must be zero, and the net torque must also be zero.Stand straight with your heels, back, and head against a wall. A small drawbridge, showing the forces on the hinges (F), its weight (w), and the tension in its wires (T).8. A gymnast is attempting to perform splits. The pencil in Figure 2 and the person in Figure 8(a) are in stable equilibrium, but become unstable for relatively small displacements to the side. (a) What force must be exerted by the wind to support a 2.50-kg chicken in the position shown in Figure 12? Hence, the chicken is in very stable equilibrium, since a relatively large displacement is needed to render it unstable.
