The triple beam balance is a typical instrument used to measure the mass of various objects. It consists of three beams, each of which is provided with a single sliding weight that has a size corresponding to the gradations of the notched scale on each beam.

What is the purpose of triple beam balance?
The triple beam balance is an instrument used to measure mass very precisely. Such devices typically have a reading error of ±0.05 grams. Its name refers to its three beams, where the middle beam is the largest, the far beam of medium size, and the front beam the smallest.
How is a triple beam balance used to find mass?
To use a triple beam balance, place an object on the pan and adjust the counterweights until the pointer is balanced at the zero line. Then determine the mass by looking at the position of each counterweight. Add the masses given by each counterweight to find the total mass of the object.
How does a triple beam balance measure mass?
A triple beam balance is a device that measures the mass of an object by comparing it with a system of three counterweights. You can measure the mass of an object by learning to move the sliders and interpret the scales on each of the three beams.
How does beam balance work?
A beam balance works on the principle of moments(stated and proved above) according to which in equilibrium, the anticlockwise moment due to the weight of an object on the left pan of the beam is equal to the clockwise moment due to the standard weights of the right pan of the beam.
Does a triple beam balance measure volume?
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.
What is the difference between beam balance and spring balance?
The beam balance actually measures the mass whereas the spring balance measures the weight. We know that spring balance works on the principle of hooke’s law. But a beam balance is used to measure mass of an object. It measures the mass by comparing the mass of an object with a known mass.
What is the difference between beam balance and electronic balance?
The difference between beam balance and electronic balance are measuring device. that is true for both instruments,but when your step on an electronic scale you are determining how much your body weighs. balance beam do not measure weight instead they value mass.
What is the first step when using a triple beam balance?
What is the first step when using a Triple-Beam Balance? 1. First, zero or calibrate the balance. It is zeroed if the pointer is at the zero when the pan is empty, and the riders are all the way to the left on the beams.
What is the purpose of the balance pointer?
Pointer: The pointer determines when the object with the weights is balanced with the ones on the beams. The pointer is located to the far right of the balance connected to the three beams. The goal of the pointer is to line up the point to the -0, which is located opposite of the pointer.
How do you use a triple beam balance slide?
Move the sliders, beginning with the largest. When moving a slider causes the balance to tip, move the slider back to the previous position. Move the next slider until it tips the balance. Place is in the previous position. Move the final slider until the balance reads zero.
How many decimal places does a triple beam balance have?
There must always be two decimal places in your answer. The last one must always end in a 0 or a 5. In the single gram sliding counterweight, you must judge if the weight is exactly on the number or in between two numbers.
Can a beam balance be used on the moon?
As a triple beam balance simply compares forces, as opposed to a scale which measures a force based on some standard, it would work exactly the same on the moon as it would on Earth. This demonstrates that mass is a physical constant unaffected by gravity.
Is beam balance a lever?
First, we identify that pliers and beam balance are first class levers. And the knife is a third class lever which is a lever with the effort between load and fulcrum.
What is a beam balance for Class 6?
A beam balance is used to measure the mass. It consists of a horizontal beam, supported at its centre. The beam can move freely about its support and a pointer is attached to the centre of the beam. Two similar pans are suspended at equal distances from the centre of the beam by means of strings of equal lengths.
Is a triple beam balance more accurate than a digital balance?
A triple-beam balance is the best all-around mechanical balance with good sensitivity and high capacity. A digital scale is much faster and easier to use than a mechanical balance for weighing out small amounts of chemicals for chemistry. A 200 g digital balance with 0.01 gram accuracy will work for most labs.
Which is more accurate digital scale or triple beam balance?
Technically, some high-end digital scales can be more accurate than a triple-beam. However, I think that the difference is negligible for the amounts that go into most glaze recipes. Triple-beams are arguably more robust- this is a consideration if you’re worried about spills.
