what conditions are necessary for static equilibrium?

The condition Fnet=0 F net = 0 must be true for both static equilibrium, where the object's velocity is zero, and dynamic equilibrium, where the object is moving at a constant velocity. Below, the motionless person is in static equilibrium. The forces acting on him add up to zero. Both forces are vertical in this case.

Statics is the branch of mechanics studying forces that act on bodies in static or dynamic equilibrium. Static equilibrium is a state where bodies are at rest; dynamic equilibrium is a state where bodies are moving at a constant velocity (rectilinear motion). In both cases the sum of the forces acting on them is zero.

1 : The equilibrium constant Kc is a constant which represents how far the reaction will proceed at a given temperature. 8.2. 2 : When Kc is greater than 1, products exceed reactants (at equilibrium). ... When much less than 1 (Kc can never be negative...so when it is close to zero) the reaction hardly occurs at all.

A static analysis can only be performed if the system being simulated does not depend on time, and if the loads being applied are constant. In a dynamic analysis, the system itself, the load application, or both might change with time.

The force of static friction can be calculated by taking the coefficient of friction between the two surfaces and multiplying it by the normal force that the surface is applying to the object. On a flat surface, the normal force is equal to the force of gravity acting down on the object.

Beams. In regards to beams, if the reaction forces can be calculated using equilibrium equations alone, they are statically determinate. On the other hand, if the reaction force can't be determined using equilibrium equations only, other methods have to be used, and the structure is said to be statically indeterminate.

Dynamic equilibrium is the steady state of a reversible reaction where the rate of the forward reaction is the same as the reaction rate in the backward direction. Static equilibrium, also known as mechanical equilibrium, means the reaction has stopped. In other words, the system is at rest.

Balanced Forces: When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force. A plane will fly at constant velocity if the acceleration is zero.

Static Friction Force depends upon the mass of the object. higher the mass of the objects , higher the force required to impend motion. Static Friction Force = mass of object X friction coefficient.

An equilibrium is considered stable (for simplicity we will consider asymptotic stability only) if the system always returns to it after small disturbances. If the system moves away from the equilibrium after small disturbances, then the equilibrium is unstable.

Two bodies are in rotational equilibrium if they are at the same temperature.

Static friction is the friction that exists between a stationary object and the surface on which it's resting. Once the objects have already started moving, kinetic friction takes over.

The equilibrium constant is important because it gives us an idea of where the equilibrium lies. The larger the equilibrium constant, the further the equilibrium lies toward the products.

Answer and Explanation: The reaction offered by the support base is equal to the weight acting at the center of gravity. This is how the object on the support base, maintains a stable equilibrium. This is the relationship between the centre of gravity and the support base for an object in a stable equilibrium.

Two substances/systems are said to be in thermal equilibrium if when separated by a diathermic wall, there is no net energy transfer between them. A system is said to be in thermodynamic equilibrium, if there is no net change in it's macroscopic properties with time.
