Why a spring balance does not give correct measurement?

Why a spring balance does not give correct measurement?

When a spring balance has been used for a long time, it starts loosing its elastic strength, i.e., an elastic fatique is developed in the spring of spring balance. The spring of such a balance takes longer time to regai its original configuration. Therefore, such spring balance will not give ac curate measurement.

How is spring balance used to measure weight?

Spring balances provide a method of mass measurement that is both simple and cheap. The mass is hung on the end of a spring and the deflection of the spring due to the downwards gravitational force on the mass is measured against a scale.

When you put an object on spring balance What do you measure?

weight
Spring balance is used to measure the weight (force acting) of the object. The working principle of the spring balance is Hooke’s law.

When you put an object on a spring balance do you get the mass of an object or its weight?

It works by Hooke’s Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position. Therefore, the scale markings on the spring balance are equally spaced. A spring scale cannot measure mass, only weight.

Why do spring balance show wrong readings after long use?

spring balance show wrong readings after long use because it’s spring becomes loose due to which the marking goes down… this is because of continous usage , the wire loses its elasticity and does not regain its original configuration. this is why it shows wrong readings.

Why does a spring balance give wrong reading after long use?

Why do spring balances show wrong readings after they have been used for a long time? When spring balances have been used for a long time, elastic fatigue is developed. So, the spring balances will no longer show the right readings.

What is the main use of a spring balance?

Main uses of spring balances are to weigh heavy loads such as trucks, storage silos, and material carried on a conveyor belt. They are also common in science education as basic accelerators. They are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness.

What will happen if you keep on adding more padlocks to the spring balance?

Answer. Answer: The spring balance is that the spring will sag because it will be heavy to lift the spring balance on the padlock. The spring balance will be heavy due to the force carried by the padlock.

Can spring balance be used to measure mass?

Spring balance is a mechanical device used for measuring the weight or force of an object by opposing the force of gravity with the force of an extended spring. Note – Spring balance measures the weight of an object but not used for mass.

When you put an object on a spring balance what do you measure * weight force mass acceleration?

Spring balance is used to measure the weight (force acting) of the object. The working principle of the spring balance is Hooke’s law.

How does a spring balance weighing scale work?

Spring scale. A spring scale or spring balance or newton meter is a type of weighing scale. It consists of spring fixed at one end with a hook to attach an object at the other. It works by Hooke’s Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position.

Are there different sizes of spring balances?

Spring balances come in different sizes. 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.

Can a spring balance be calibrated for accuracy?

A spring balance can be calibrated for the accurate measurement of mass in the location in which they are used, but many spring balances are marked right on their face “Not Legal for Trade” or words of similar import due to the approximate nature of the theory used to mark the scale.

What kind of weight system do they use to weigh gold?

The Troy weight system is the universal system used to weigh gold (and silver). Unlike the Avoirdupois weight system, the system commonly used in the United States that is based on 16 ounces to the pound, the Troy weight system is a series of units of weight based on a pound of 12 ounces and an ounce of 20 pennyweights or 480 grains.
