A beam balance, also known as a double-pan balance, is a type of weighing scale used to measure the mass of an object. It consists of a balanced beam with two pans suspended from its ends, one for the object to be weighed and the other for weights to be added or removed to balance the scale. The beam balance uses the principle of balance to determine the mass of an object by comparing it to a known reference weight.
Beam Balance
A beam balance is a type of mechanical scale used to measure the mass or weight of an object under gravity. It consists of a balanced beam with two pans attached to either end, one for holding the object to be weighed and the other for reference weights.
The beam balance works by comparing the unknown mass of the object to a known reference weight and determining the point of balance on the beam, which indicates the mass of the object.
The beam balance uses the principle of balance and is a simple, accurate, and reliable tool for measuring weight in various applications.
Determination of Mass of Two Different Object by Using a Beam Balance
To determine the mass of two different objects using a beam balance, follow these steps:
- Place the first object on one pan of the beam balance.
- Add reference weights to the other pan until the beam is balanced. The weights should be added or removed in small increments to ensure accuracy.
- Once the beam is balanced, the reference weights on the other pan indicate the mass of the object. Record this value.
- Remove the first object and place the second object on the pan.
- Repeat steps 2 and 3 to determine the mass of the second object.
Note: It is important to make sure that the beam balance is calibrated correctly and that the reference weights are accurate before using it to determine the mass of an object.
Aim
Determine the mass of two different object by using beam balance.
Apparatus Used
The apparatus used to measure the mass of two different objects using a beam balance include:
Beam Balance
Weight Box
Beam Balance of different Masses
Beam balance: The beam balance is the main apparatus used in this process. It is a type of mechanical scale with a balanced beam and two pans attached to either end.
Objects to be weighed: The two different objects that need to be weighed.
Calibration mass: A calibration mass is a standard weight used to calibrate the beam balance and ensure its accuracy.
Diagram
Theory
By using the principle of moments beam balance calculate the gravitational mass of a body
(Load) * (Load arm) = (Effort) * (Effort arm)
m1g × a1 = m2g × a2
m1a1 = m2a2
Let,
m1 = Gravitational mass of body placed in the left of pans and m2 = Standard weight placed in the right of pans for keeping the beam balance, a1 = a2, then m1 = m2.
Procedure
The procedure for using a beam balance typically involves the following steps:
Set up the beam: Mount the beam on a stable base or pivot point. Ensure that the pivot is centered and secure.
Calibrate the beam: If necessary, adjust the counterweights on the beam until it is level and in a state of balance.
Place the object to be weighed: Carefully place the object to be weighed on one end of the beam.
Observe the beam: Observe the movement of the beam and note any tilting or imbalance.
Adjust the counterweights: If necessary, adjust the counterweights on the opposite end of the beam until the beam is level and in balance.
Read the measurement: The position of the counterweights on the beam can be used to determine the weight of the object. Some beam balances have marked increments that allow for a direct reading of weight, while others may require calculation based on the distance of the counterweights from the pivot point.
Repeat the procedure: Repeat the procedure for any additional objects to be weighed.
It is important to follow proper safety procedures when using a beam balance, including securing the object to be weighed and ensuring that the beam is stable and secure before making any measurements.

A beam balance is a type of mechanical scale used to measure the mass or weight of an object under gravity Mass is a fundamental property of matter that measures the amount of matter in an object.Mass is a scalar quantity, which means it has only magnitude and no direction.Mass is typically expressed in units of grams (g) or kilograms (kg). The principle of a beam balance is based on the law of moments. A true balance, also known as an analytical balance, is a type of balance that is used to accurately measure the mass of an object to a very high degree of precision. True balances work on the principle of equal arm length and equal pans weight. Determine Mass Of Two Different Objects By Using A Beam Balance FAQs
