How do you use a triple beam balance in a lab?
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.
What happens to the pointer on a triple beam balance?
One weighs an object on the pan by counterbalancing it with the weights on the beams. When the weights match exactly – indicated by the pointer pointing to zero – the weight of the object is then read off of the beams.
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.
How does a beam balance work?
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 maximum mass this triple beam balance can measure?
610 grams
Q: What is the maximum mass this triple beam balance can measure? A: The maximum mass it can measure is 610 grams (500 grams + 100 grams + 10 grams). 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.
What is the uncertainty of the triple beam balance?
Here are some typical uncertainties of various laboratory instruments: Meter stick: ± 0.02cm. Vernier caliper: ± 0.01cm. Triple-beam balance: ± 0.02g.
What is beam balance used to measure?
mass
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 are the steps for using a triple beam balance?
Start with the two heavier weight poises and then use the lightest one to do the fine tuning. Our triple beam balance and the Ohaus triple beam balance are accurate to 0.1 grams. To read the weight of an object in grams, add up the number that each weight poise is at when the pointer zeroes.
How do you use a triple beam balance?
Instructions on use The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero. Once the balance has been calibrated, place the object to be measured on the pan.
What are the uses of triple beam balance?
A triple beam balance is used to measure the mass of objects. The machine is very precise and has a reading error of +/- 0.05 grams. The machine gets its name due to its three beams, which all carry weights. The front beam reads continuously up to 10 grams, and the middle beam always reads in 100-gram increments.
What is the function for a triple beam balance?
Triple beam balance scales function by balancing an object with three counterweights that are attached to the scale to accurately measure the object’s weight. Using one of these devices is not difficult but following these steps consistently will help to ensure accuracy.
