Common balance is used to find unknown mass by using known standard masses. By adjusting levelling screw the plumb line is brought just above the pointed projection on the balance. The beam is raised using the lever and checked that the pointer swings equally on either side of the zero mark.
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.
A beam balance is a device used to measure mass. An object is put into a disk on one side that hangs from one end of a bar. It is balanced with weights at the other end. It has a lever with two equal arms and a pan suspended from each arm.

Class 1 levers have the fulcrum in between the load and the effort. Examples are seesaw, pair of scissors, a pair of pliers, a common beam balance. Class 2 levers have the fulcrum at one end.
A physical balance can be used to measure both mass and weight of an object.
While the designs of various triple beam balance models differ slightly, they have two basic components in common: the base and the pan. The base is a long metal platform which supports the rest of the apparatus. When moving the triple beam balance, place your hands on either side of the base for stability.
For Best Results with a Triple Beam Balance:Before you weigh something, 'zero' the balance. Do this by sliding back all the weight poises (that slide along the beams) so that the pointer is right at the zero line. You might need to turn the zero adjustment knob a little bit to get it right at the line.
If the front slider is between two marks, estimate where it's pointing. For example, if the middle slider is in the 200-gram notch, the rear slider is in the 10-gram notch and the front slider is halfway between the 2-gram and 3-gram notches, you would total 200 grams plus 10 grams plus 2.5 to get 212.5 grams.
The very basic principle that makes a balance a balance and not a scale is still the same: a counteracting force is created to be compared to the unknown mass. The weighing pan is attached to an electromagnetic coil, through which electric current is flowing. The coil floats in a magnetic field created by an amplifier.
The mass is essentially "how much stuff" is in an object. Weight: There is a gravitational interaction between objects that have mass. If you consider an object interacting with the Earth, this force is called the weight. The unit for weight is the Newton (same as for any other force).
If we used a triple beam balance on the Moon, what would it tell us that is important in physics? The balance would report the exact same values as it would on Earth. So even though the beam balance and the spring balance report the exact same values here on Earth, they'd produce very different readings on the Moon.
Where and what is a fulcrum on a triple beam balance? The fulcrum is somewhere between the pan and the beams, as the other gents have said. The fulcrum is usually referred to as a “knife edge” in balances.
If your balance needs to be calibrated:
- First, remove the screw on the side, underneath the pan. This holds the pan in place.
- Next, unscrew the weighing pan to access the weights inside.
- If the weight is too high, remove weight from the inside of the balance.
- After the weight is correct, reassemble the balance.
A triple beam balance is a device that measures the mass of an object by comparing it with a system of three counterweights. The advantage of using this system is it allows you to measure the weight of an object extremely precisely.
In the metric system, we use the following base units: Mass is measured in GRAMS, using a triple beam balance or scale. Volume is measured in LITERS, using a graduated cylinder for liquids. Measuring Mass with a Triple-Beam Balance A triple-beam balance has a pan and three beams with sliding masses called riders.
Adjustment, usage and maintenance of double beam balance
- Choose a suitable smooth and stable table and put the balance on it.
- Adjust the fine-tuning balancing knob at the right end of the beam, set the pointer of the Balance to equilibrium position zero.
- Put the article to be weighted on the left pan of the balance.
An electronic balance is the most common method for determining a sample's mass. The balance detects this downward movement and generates a counterbalancing force by increasing the current to the electromagnet. The current returning the balance to its null point is proportional to the object's mass.
Mass by Difference or Subtraction
- Zero the scale or press the tare button. The balance should read "0".
- Measure the mass of the sample and container.
- Dispense the sample into your solution.
- Measure the mass of the container.
- If you repeat the process and use the same container, do not assume its mass is the same!
A triple beam balance is a type of lever that is used to measure mass, or the amount of matter in an object. An object with an unknown mass is placed on the measurement tray. On the other side of a fulcrum, a set of sliding weights, called riders, slide on beams to balance the object.
Q: What is the smallest mass this triple beam balance can measure? A: The smallest mass it can measure is one-tenth (0.1) of a gram.
The triple beam balance is an instrument used to measure mass very precisely. Typically, the reading scale of the middle beam reads in 100 gram increments, the far beam in 10 gram increments, and the front beam can read from 0 to 10 grams.
The triple beam balance is a very accurate instrument and can measure within a tenth of a gram. However, the double beam is only as accurate as the smallest weight being used. For example; if the smallest weight you have is a 5-gram weight, then you can only estimate the weight of an object to the nearest 5 grams.
Are triple beam scales illegal? Cocaine and marijuana are contraband, meaning the possession of it is always illegal. However, a triple beam scale is a legitimate subject of private ownership and is not contraband.
The middle (heaviest) rider should be moved first. This rider measures the largest unit of mass used.
A scale or balance is a device to measure weight or mass. These are also known as mass scales, weight scales, mass balances, weight balances.
