Balance Beam Scale How To Use
Balance beam scales are the most accurate and common method of measuring the weight of an object or person.
Balance beam scale how to use. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum one plate holds an object of unknown mass or weight while known masses are added to the other. Watch the balance beam. Slide the small weight slowly along the scale. Common balance or physical balance are mostly used devices for the measurement of mass.
You will feel small notches along the scale where the sliders can rest at each weight increment. Pointers the scale pointer marks the equal point of the object s mass on the scale and mass on the beam. Before using triple beam balance the scale pointer should be at zero. Spring balance table balance platform balance roman steelyard triple beam steelyard are a few of the other types of balance.
Most middle school students learn to use a triple beam balance scale at some point during their science classes. A beam balance or beam scale is a device to measure weight or mass these are also known as mass scales weight scales mass balances weight balances or simply scales balances or balance scales. Zero adjustment knob this is used to manually adjust the triple beam balance to the zero mark check to ensure that the pointer is at zero before use. Measurement of mass by use of beam balance.
Once at the correct weight it should come to a stop completely horizontal with the needle in the center of the slot as it did when the scale was at zero. Often used by science teachers to demonstrate the principle of mass these devices can.
