The beam balance is a device used for the determination of the mass of a body under gravitation. Beam balance is used for high precision measurements like masses up to 250g, it consists of a pair of scale pans one at each end of a rigid beam.

What does a beam balance measure?
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.
How does the beam balance works?
Beam balances use an application of the lever principle. Something called a fulcrum is placed between the force exerted by the counterweights and the load. … The counterweights move the beam up or down, so the balance’s pointer moves from the zero point when properly calibrated.
What is the function of a balance scale?
A scale or balance is a device to measure weight or mass. These are also known as mass scales, weight scales, mass balances, and weight balances.
How do you balance a pan at home?
Is weight is measured by beam balance?
A beam balance does not measure mass; it measures weight. The gravitational force of attraction between the earth and an object depend on the mass of the object.
How do I read a triple beam balance?
What units does a triple beam balance measure?
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. Distance is measured in METERS, using a ruler or meter stick.
How do you adjust a triple beam balance?
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.
Why is the triple beam balance important?
A triple beam balance provides greater accuracy than a spring scale in determining the mass of objects in grams. The balance can measure the mass of objects up to 610 grams in weight. Its accuracy is well-suited to most laboratory uses, finding the mass of any object with a margin of error of only .
How will you ensure that a beam balance is correct?
A beam balance is said to be true if its beam remains horizontal when its pans are empty or equal weights are placed on them.
What are the different types of balances?
There are actually three types of balances: the equal arm balance, the unequal arm balance, and the spring balance.
What is the main function of analytical balance?
Analytical balances are highly sensitive lab instruments designed to accurately measure mass. Their readability has a range between 0.1mg – 0.01mg. Analytical balances have a draft shield or weighing chamber to prevent the very small samples from being affected by air currents.
What is the function of an electronic balance?
Electronic balance is an instrument used in the accurate measurement of weight of materials. Electronic balance is a significant instrument for the laboratories for precise measurement of chemicals which are used in various experiments. Laboratory electronic balance provides digital result of measurement.
What is a normal weighing balance?
Standard precision balance – 0.01g – 0.001g (2-3 decimal places) Analytical balance – 0.0001g (4 decimal places) Semi-micro balance – 0.00001g (5 decimal places) Microbalance – 0.000001g (6 decimal places)
How do you balance your weight?
- Use a hole punch to make holes in 2 small paper cups. Punch 2 holes in each cup. …
- Cut 2 pieces of twine that are each around 1 foot (0.30 m) long. Any kind of twine will work, but a thick, strong twine will make the balance scale more durable. …
- Tie the ends of the twine through the holes in the cups.
What does Ballance mean?
noun. a state of equilibrium or equipoise; equal distribution of weight, amount, etc. something used to produce equilibrium; counterpoise. mental steadiness or emotional stability; habit of calm behavior, judgment, etc. a state of bodily equilibrium: He lost his balance and fell down the stairs.
What is Pan balance?
n. 1 a weighing device, generally consisting of a horizontal beam pivoted at its centre, from the ends of which two pans are suspended. The substance to be weighed is placed in one pan and known weights are placed in the other until the beam returns to the horizontal.
Which is the unit of weight?
newton The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.
What is difference between beam balance and physical balance?
A beam balance compares the mass of two object whereas the physical balance is used to measure the mass of an object with respect to a known unit.
Which balance is used to measure the weight of a body?
Beam balance Solution : Beam balance is commonly used to measure the mass of a body.
How do you read a four beam balance?
How do you read a pan balance?
Which rider on the balance should be moved first?
middle The middle (heaviest) rider should be moved first. This rider measures the largest unit of mass used.
What does a triple beam balance measure in grams?
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.
What is double beam balance?
A double beam balance, also called a double pan balance, is a scale that acts like a see-saw and gets its name from the two pans or balances on either side of a fulcrum.
Is beam a balance?
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.
How do I calibrate my balance?
Close the door and tare the balance by pressing the Tare button. Allow the reading to settle for a few seconds to ensure the balance reads zero. Choose one or more weights to calibrate the balance with. These weights should be standardized to an exact weight.
What are the steps in a triple beam balance?
Place balance on a smooth, flat surface. Slide the separate sliding weight up into the slot on the back side of the center beam. Angle the sliding weight until it is attaches correctly to the beam. Move all the sliding weights to the zero position.
