What are the types of balance scale?
There are actually three types of balances: the equal arm balance, the unequal arm balance, and the spring balance. The equal arm balance is named such because the distance between the pivot and each end of the bar are equidistant, or separated by an equal length from the pivot point.
What is a balancing scale called?
These are also known as mass scales, weight scales, mass balances, and weight balances. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum.
What are the 2 types of balances?
Balance is the attainment of optical and pyschological equilibrium in a composition. There are two types of visual balance: Symmetrical and Asymmetrical. Symmetrical balance refers to an even distribution of visual weight on either side of an axis. Asymmetrical balance refers to a pyschological or “felt” balance.

What is a balance scale in math?
A device for weighing. When the pans contain exactly the same mass the beam is in balance. You can place an object in one pan and standard weights in the other to find what the object weighs.
Which is the correct description of a balance scale?
Weighing scale. A Beam balance (or Beam scale) is a device to measure weight or mass. These are also known as mass scales, weight scales, mass balance, weight balance, or simply scale, balance, or balance scale. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum.
How are balances different from spring based scales?
Unlike spring-based scales, balances are used for the precision measurement of mass as their accuracy is not affected by variations in the local gravitational field. (On Earth, for example, these can amount to ±0.5% between locations.)
What are the different types of balances used for?
The simplest type of balance, the equal-arm, or beam, balance has been used for many thousands of years as an application of a simple lever. The Beam, Fulcrum and Pointer. A uniform bar, the beam, is suspended at its exact center on a knife-edge hinge set at right angles to it. This point of support is called the fulcrum.
Why are they called triple beam balances and scales?
They are called triple-beam balances because they have three decades of weights that slide along individually calibrated scales. The three decades are usually in graduations of 100g, 10g and 1g. These scales offer much less readability but are adequate for many weighing applications.
