Proper usage and audio pronunciation (plus IPA phonetic transcription) of the word spring balance. The two balances are now so arranged that the hanging mass m is fully immersed inside the liquid in the beaker as shown in the figure. For example, In a spring balance having a range of 0 to 25 kilograms, it can be observed that each kilogram on the scale is divided into ten equal parts. A spring scale will only read correctly in a frame of reference where the acceleration in the spring axis is constant (such as on earth, where the acceleration is due to gravity). The largest spring balance ranges between 5000 and 8000 newtons. 1. spring balance - a balance that measure weight by the tension on a helical spring. Generally, small scales that measure newtons will have a less firm spring (one with a smaller spring constant) than larger ones that measure tens, hundreds or thousands of newtons or even more depending on the scale of newtons used. A spring balance has a scale that reads from 0 to 50kg. Spring balance is a device used for measuring force on the object It has a spring attached to a hook. Meaning of spring balance. When a specimen is placed on the pan the spring stretches along a calibrated scale and a pointer indicates the weight. balance - a scale for weighing; depends on pull of gravity. These balances work by using stainless steel, coiled spring as a counterbalance. The scale on top would read slightly heavier due to also supporting the weight of the lower scale itself. The principle underlying the spring balance was first investigated in the seventeenth century by Robert Hooke. Therefore, the scale markings on the spring balance are equally spaced. Spring balance is a device used to measure the weight of small bodies. I t consisits of a spring to hang the weights. A spring balance may be labeled in both units of force (poundals, Newtons) and mass (pounds, kilograms/grams). There is a direct relationship between how much the spring extends and the force required to extend it. A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extended spring. The Newton spring balance supported from a metal frame When a force is applied to the spring it extends; the larger the force, the greater the extension.
