What are the parts of a spring scale?
spring balance. Scale made up of a hook attached to a spring that stretches in proportion to the weight of the object being weighed.
How do you calculate spring scale?
It is calculated by dividing the change of force by the change in spring extension. For the example in the figure below, this is calculated by dividing 5 newtons by 50 mm, which gives a spring constant for this Newton spring balance of 0.1 newtons per mm extension.
What are spring scales used for?
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 is the purpose of a spring scale?
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. A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extended spring.
What is spring balance in units of measurement?
As with the Units of Measurement Wiki, the text of Wikipedia is available under Creative Commons License see Wikia:Licensing . The spring balance (also known as spring scale) is simply a spring fixed at one end with a hook to attach an object at the other.
How does the weight of a spring scale work?
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.
How does the force of a spring work?
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 scale are equally spaced.
Why are the markings on a spring scale equally spaced?
Therefore the scale markings on the spring scale are equally spaced. Spring scales can be calibrated for the accurate measurement of mass in the location in which they are used, but many spring scales 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.
