spring scale measures

These small spring scales are also sometimes used in the classroom to educate children about weights and measures, and to introduce students to the basic properties of springs. With the explanation given, I would suppose that you take the resting position of the spring, then measure its final position when it is compressed, and use that ratio to determine the amount of applied force. They are also common in science education as basic accelerators. The big advantage to this type of scale is that it is cheap and very easy to use. The scale's dial reflects the amount of deflection experienced by the spring, indicating how much force was exerted on the spring to cause it to move. 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). @hamje32 - I think your explanation of a spring weight scale is correct. Small scales with sensitive springs can be used to measure differences of up to a gram or less, though these will break if heavy weights were attached to them.

The largest spring scale ranged in measurement from 5000–8000 newtons.

The primary disadvantage is that spring scales are not always very accurate, and they are subject to wearing down over time, which causes the scale to register weights incorrectly. I take it then that typical bathroom balance scales operate by the same mechanism and principle, except that in this case the deflection would be inward and not outward. Spring scales are used in many settings where people need to quickly weigh things, and pinpoint accuracy is not necessarily needed.

Strictly speaking, only the force values are correctly labeled. x .05Lb, 10N x 0.25N, Taylor Precision Products Dial Style 70-Pound Industrial Hanging Scale, Taylor Precision Products Hanging Scale (280-Pound/128-Kilogram), Polysun American Weigh Scale Digital LED Screen Spring Hanging Scale 10g,50kg, Ajax Scientific Plastic Tubular Spring Scale, 250g/2.5N Weight Capacity, Blue, Taylor Precision Products Hanging Scale (70-Pound/32-Kilogram), Ajax Scientific Plastic Tubular Spring Scale, 1000g/10N Weight Capacity, Brown, United Scientific Supplies SB5000-P Spring Scale, 100 g / 1N, 17.78" Length, Yellow, Tubular Spring Scales Grams/Newtons - 500g/5N Green, Ajax Scientific Plastic Tubular Spring Scale, 500g/5N Weight Capacity, Green. If two or more spring balances are hung one below the other in series, each of the scales will read approximately the same, the full weight of the body hung on the lower scale.

As long as the spring in good condition, the spring scale will be reasonably accurate. Spring balances come in different sizes. Spring scales can be used to measure weight in a wide range, depending on the stiffness of the particular spring. How do we know that these are accurate?

More importantly, however, I’d love to know if a digital spring scale is anymore accurate than one that is not digital? Frankly, I am more concerned about the accuracy of the hanging scales in the supermarket when I go to buy produce. Several companies sell portable spring scales with hooks which can be tremendously useful. x .25Lb, 50N x 1N, Ohaus 8011-MA Dial-Type Hanging Spring Scale, 250g x 2g, 9 oz x 1/8 oz, SEOH Spring Scale Metric/Newton 255gm / 2.5N for Physics, Eisco Labs Newton Force Meter Spring Scale - Max Capacity 50N, 5Kg, Dual Scale Labeled, Newton Force Meter Spring Scale, 10N Newton Meter Spring Dynamometer Bar Physics Mechanical Experiment Instrument with Premium Quality, Eisco Labs Newton Force Meter Spring Scale - Max Capacity 30N, 3Kg, Dual Scale Labeled, Ohaus 8004-MN Pull-Type Hanging Spring Scales, 2000g x 50g, and 20N x 0.5N, Ohaus 8001-MN Pull-Type Hanging Spring Scales, 250g x 10g, and 2.5N x 0.1N, MODERN STEP Hanging Scale 660Lb 300Kg for Farm, Hunting, Bow Draw Weight, Big Fish & Hoyer Lift with Accurate Sensor (Digital, Professional, Light Case), Ohaus 8016-00 Dial-Type Hanging Spring Scale with Demonstration Dial 20N x 1/2N, Weston Spring & Hook Scale, 150 lb , Anodized Aluminum, Non-Slip Grip, Patented, 2kg / 20N Push Pull Balance - Tubular - Acrylic - Eisco Labs, Ohaus 8002-MN Pull-Type Hanging Spring Scales, 500g x 20g, and 5N x 0.2N, Hanging Scale 660Lb 300Kg for Farm, Hunting, Bow Draw Weight, Big Fish & Hoyer Lift with Accurate Sensor (Aluminum Heavy Duty Case, Digital), Pesola Medio-Line Spring Scale, 300g x 2g, Fish Scale,JOOKKI Hanging Scale Portable Dial Scale LCD Digital Weight Electronic Scale 110lb/50kg with a Tape Measure for Tackle Bag,Luggage,Baggage,(Black), Arboleaf Weight Scale - Smart Scale Bluetooth Body Fat Scale Wireless with iOS, Android APP, Unlimited Users, Auto Recognition, 10 Body Composition Analyzer, Fat, BMI, BMR, Muscle Mass, 396 lb - Black, Arboleaf Smart Scale - Wi-Fi & Bluetooth Weight Scale, 14 Body Composition Monitor with iOS Android APP, Wireless Cloud-Storage for Unlimited Data & 8 Users, BMR BMI Scales Digital Weight and Body Fat, Ajax Scientific 3 Piece Spring Balance Set, Ohaus 8004-MA Pull-Type Hanging Spring Scales, 2000g x 50g, 72 oz x 2 oz, Ajax Scientific Plastic Tubular Spring Scale, 2000g/20N Weight Capacity, Red, Arboleaf Digital Scale - Bluetooth Smart Scale Bathroom Weight Scale, Body Fat Monitor, 10 Key Composition, iOS Android APP, Unlimited Users, Auto Recognition, BMI, BMR, FITINDEX Smart Body Fat Scale, Digital BMI Weight Wireless Scale, Body Composition Monitor with Smartphone App for Body Weight, Body Fat, Muscle Mass, 396lbs - Black, Pesola Medio-Line Spring Scale, 2,500g x 20g, w/Hook End, Eisco Labs Newton Force Meter Spring Scale - Max Capacity 5N, 500gm, Dual Scale Labeled, Ohaus 8004-PN Pull-Type Hanging Spring Scales, 4.5Lb.

A spring scale is a scale which measures weight by determining the deflection of a spring. After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in. I would be open to correction, however. Over 25 percent? exciting challenge of being a wiseGEEK researcher and writer. They are also common in science education as basic accelerators.

You’re seeing this ad based on the product’s relevance to your search query. This lightweight scale design is useful for people doing field work, as it allows them to weigh objects in the field without needing to carry around a large scale. I don’t know that inspectors check the scales, but I’d think that there would have to be some quality control standards somewhere.

It consists of a spring fixed at one end with a hook to attach an object at the other. Main uses of spring balances are to weigh heavy loads such as trucks, storage silos, and material carried on a conveyor belt. I’m not a genius to have figured this out, but it seems to follow logically from the explanation in this article.

They also applied the same spring balance principle to steam locomotive safety valves, replacing the earlier deadweight valves.

@hamje32 - Everyone would like to know how accurate those bathroom scales are; weight is such a touchy subject after all.
