Dynamic balancing is the process of adjusting the balance or eliminating vibration in rotating objects by adding or subtracting weight. It is commonly used in high-performance situations and can balance objects within one or two grams. It is used in various machines, including household items, to provide long-lasting, smooth operation. Dynamic balancing is the practice […]
Thermal equilibrium occurs when two objects reach the same temperature and stop exchanging heat energy. Heat flows from hotter to cooler objects until equilibrium is reached. This concept is important in chemistry and nature, where balance is crucial for vital chemical reactions to occur. Thermal equilibrium is achieved when two objects or systems reach the […]
Static equilibrium occurs when the total forces acting on a stationary object add up to zero, resulting in no motion. This requires both translational and rotational equilibrium, with external forces and torques adding up to zero. Newton’s first law of motion applies, stating that an object will remain at constant velocity if the vector sum […]
Fluid in hydrostatic equilibrium has a balanced downward force from gravity and upward force from fluid pressure. The hydrostatic equilibrium equation can calculate pressure in a planetary atmosphere. A volume of gas in space contracts under gravity until nuclear fusion produces a star in hydrostatic equilibrium. Stars eventually run out of hydrogen and collapse, leaving […]
Hydrostatic equilibrium is used to measure the weight and density of substances using a hydrostatic balance, which compares the weight of an object in air and water. This technology can detect impurities and is used in fields such as gemology and astrophysics. Modern devices use electronic sensing and offer precision readouts and unit conversions. If […]
Chemical equilibrium is a stable relationship between reactants and products in a reversible reaction. The rate of a reaction is affected by temperature, phase, and catalysts. Chemical bonds form new substances with unique properties. All reactions are reversible to some extent, but some have a non-negligible degree of reversibility. The rate at which equilibrium is […]
Break-even analysis calculates the amount of revenue needed to cover all costs of operating a business. It includes identifying all expenses, comparing total costs to total sales, and using the analysis to forecast projections and make adjustments. A break-even analysis is a valuable calculation that is useful for both large and small business accounting. Essentially, […]
A Nash equilibrium is a solution in game theory where no player is better off changing their action, commonly used in economics. It can be seen in the example of two companies setting prices for the same product, but real-world conditions can complicate matters. Nash equilibria can force firms to compete in other ways, but […]
Dynamic equilibrium is a state where the ratio of products to reactants remains constant due to the equal rates of forward and reverse reactions. Reversible reactions favor both reactants and products, and Le Châtelier’s Principle explains how changes in variables can shift the equilibrium position. It is linked to the rate of chemical reactions and […]
Gross Domestic Product (GDP) is the total financial value of all goods and services produced in a country within a year. Equilibrium GDP is when aggregate demand and supply are equal. Changes in aggregate demand and supply affect equilibrium GDP, which changes over time. Gross Domestic Product (GDP) is an important economic indicator used to […]
The adjusted balance method calculates interest on financial accounts based on the previous closing balance, without taking into account new expenses during the billing cycle. It can result in lower charges and is the basis for interest-free periods on credit cards. Variations include the previous balance and two-cycle balance methods, while the average daily balance […]
