For an object to be in equilibrium, it must be experiencing no acceleration. This means that both the net force and the net torque on the object must be zero. Here we will discuss the first condition, that of zero net force.

What condition or conditions must be met for a rigid body to be in rotational equilibrium? Both the net force and net torque on the object must be zero.

A solid body submitted to three forces whose lines of action are not parallel is in equilibrium if the three following conditions apply : The lines of action are coplanar (in the same plane) The lines of action are convergent (they cross at the same point) The vector sum of these forces is equal to the zero vector.

A simple mechanical body is said to be in equilibrium if it experiences neither linear acceleration nor angular acceleration; unless it is disturbed by an outside force, it will continue in that condition indefinitely.

The second condition necessary to achieve equilibrium is that the net external torque on a system must be zero: netτ=0. By convention, counterclockwise torques are positive, and clockwise torques are negative.

The sum or resultant of all external forces acting on the body must be equal to zero. The sum or resultant of all external torques from external forces acting on the object must be zero.

2. Which one is not the condition for the equilibrium in free body diagram for calculation of the normal forces, consider all forces to be straight and linear? Explanation: For the equilibrium in the three dimensional system of axis we have all the conditions true as, ∑Fx=0, ∑Fy=0 and ∑Fz=0.

net torque

Yes, a body can be in equilibrium if it is in motion. We call this type of equilibrium as a dynamic equilibrium. We know that a body is said to be in equilibrium if the net force acting on it is zero. By the second law of motion, we know that the acceleration in such bodies is zero.

If there is only one external force (or torque) acting on an object, it cannot be in equilibrium. True, as the sum of forces cannot be zero in this case unless the force itself is zero. If an object is in equilibrium there must be an even number of forces acting on it.

If a body is in at rest, resultant force is zero. If a body is moving with uniform velocity, still the resultant force is zero. Similarly a rotating ceiling fan is in equilibrium as net torque acting on it is zero.

Catalyst has no effect on equilibrium state. The reaction never cease at equilibrium because equilibrium is dynamic in nature.

Organisms Are Never at Equilibrium with Their Surroundings The molecules and ions contained within a living organism differ in kind and in concentration from those in the organism’s surroundings. Without energy, the dead body cannot maintain concentration gradients; ions leak out.

The equilibrium state is one in which there is no net change in the concentrations of reactants and products. Despite the fact that there is no apparent change at equilibrium, this does not mean that all chemical reaction has ceased.

First Law: When a body is in equilibrium, the vector sum of the forces acting on it is zero. Second Law: When a body is in equilibrium, the sum of the moments about any point is zero. The sum of the clockwise and the anticlockwise moments, to two significant figures, is zero.

There are two kinds of mechanical equilibrium:

• static equilibrium and.
• dynamic equilibrium.

Equilibrium is the state in which market supply and demand balance each other, and as a result prices become stable. Generally, an over-supply of goods or services causes prices to go down, which results in higher demand—while an under-supply or shortage causes prices to go up resulting in less demand.

The point of equilibrium represents a theoretical state of rest where all economic transactions that “should” occur, given the initial state of all relevant economic variables, have taken place.

Types of Economic Equilibrium As defined in microeconomics – which studies economies at the level of individuals and companies – economic equilibrium is the price in which supply equals demand for a product or service. There is a supply curve and demand curve. That point represents the economic equilibrium.

A market is in equilibrium if at the market price the quantity demanded is equal to the quantity supplied. The price at which the quantity demanded is equal to the quantity supplied is called the equilibrium price or market clearing price and the corresponding quantity is the equilibrium quantity.

The equilibrium price in any market is the price at which quantity demanded equals quantity supplied. The equilibrium price in the market for coffee is thus $6 per pound. The equilibrium quantity is the quantity demanded and supplied at the equilibrium price.

An increase in demand and a decrease in supply will cause an increase in equilibrium price, but the effect on equilibrium quantity cannot be detennined. For any quantity, consumers now place a higher value on the good,and producers must have a higher price in order to supply the good; therefore, price will increase.

The equilibrium price is the only price where the plans of consumers and the plans of producers agree—that is, where the amount of the product consumers want to buy (quantity demanded) is equal to the amount producers want to sell (quantity supplied). This common quantity is called the equilibrium quantity.

If demand increases and supply increases then equilibrium quantity goes up, and equilibrium price could go up, down, or stay the same. If demand increases and supply decreases then equilibrium quantity could go up, down, or stay the same, and equilibrium price will go up.

Essentially, a change in supply is an increase or decrease in the quantity supplied that is paired with a higher or lower supply price. A change in supply can occur as a result of new technologies, such as more efficient or less expensive production processes, or a change in the number of competitors in the market.

The rise and fall of fads will affect the equilibrium price and quantity for example if water was in short supply then the price will more than likely go up. Hope this helps!
