A child’s seesaw, shown in

, is an example of static equilibrium. An object in static equilibrium is one that has no acceleration in any direction. While there might be motion, such motion is constant. Two children on a seesaw: The system is in static equilibrium, showing no acceleration in any direction.

What is an example of static equilibrium?

1: In a torque balance, a horizontal beam is supported at a fulcrum (indicated by S) and masses are attached to both sides of the fulcrum. The system is in static equilibrium

when the beam does not rotate

. It is balanced when the beam remains level.

What is called static equilibrium?

Static equilibrium takes place

when all the forces acting on an object are balanced and the object is not in motion in relation to the relative plane

. An object which is in static equilibrium is unable to move. This is because all the forces which act on it compensate for one another.

Where is the static equilibrium?

An object is in static equilibrium if and only if:

The sum of the forces on it in each direction is zero

. The sum of the torques on it in each direction is zero. Its linear momentum is zero (i.e. it’s not moving).

What are the three conditions for static equilibrium?

static equilibrium: The state in which a system is stable and at rest. To achieve complete static equilibrium, a system must have

both rotational equilibrium (have a net torque of zero) and translational equilibrium (have a net force of zero)

. translational equilibrium: A state in which net force is equal to zero.

What are the 3 types of equilibrium?

There are three types of equilibrium:

stable, unstable, and neutral

. Figures throughout this module illustrate various examples. 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.

What is the connection of static equilibrium in our daily life?


The houses that we live in, the roads and bridges that we pass by in traffic, dams

, etc. All of these structures are able to maintain their statical status because they can actually keep the forces acting on them in equilibrium, in other words, they remain in static equilibrium.

What is the importance of static equilibrium?

Static equilibrium is a valuable analysis tool: for example, if two forces are acting on an object that is in static equilibrium, that means

they add up to zero

. If you know the direction and magnitude of one of the forces, you can write an equation to determine the magnitude and direction of the unknown force.

What are the equation of static equilibrium?

The first equilibrium condition for the static equilibrium of a rigid body expresses translational equilibrium:

∑k→Fk=→0

. The first equilibrium condition, Equation 12.2. 2, is the equilibrium condition for forces, which we encountered when studying applications of Newton’s laws.

What is an example of equilibrium in everyday life?

An example of equilibrium is when

you are calm and steady

. An example of equilibrium is when hot air and cold air are entering the room at the same time so that the overall temperature of the room does not change at all.

What are the 2 conditions of static equilibrium?

Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium),

and the sum of all external torques from external forces is zero

(second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium.

What is second condition for equilibrium?

The second condition necessary to achieve equilibrium involves

avoiding accelerated rotation (maintaining a constant angular velocity)

. A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it.

What is equilibrium and its conditions?

The equilibrium condition of an object

exists when Newton’s first law is valid

. An object is in equilibrium in a reference coordinate system when all external forces (including moments) acting on it are balanced. This means that the net result of all the external forces and moments acting on this object is zero.

What are the examples of stable equilibrium?


A book lying on a horizontal surface

is an example of stable equilibrium. If the book is lifted from one edge and then allowed to fall, it will come back to its original position. Other examples of stable equilibrium are bodies lying on the floor such as chair, table etc.

What is meant by equilibrium point?


The specific point where demand matches supply at the same price

. Maintained by price changes responding to shifts in supply or demand. Equilibrium is a market price with an equal amount of demand and supply for a specific product or service.

What does equilibrium constant depend on?

The equilibrium constant K

eq

of a reaction reflects the ratio of products to reactants at equilibrium and thus is a measure of the extent of the reaction. The K

eq

depends on

the temperature and pressure

, but is independent of the reaction rate and of the initial concentrations of reactants and products.
