How much a 5-pound weight would stretch the spring?
It depends on spring energy or spring strength
What is the laboratory instrument that is a special scale that measures weight?
A spring scale measures weight.
Does a spring scale measure weight?
A spring scale is any device that uses the translation of a spring by force due to weight to discover the mass of an object. Let's translate that into easier words. A spring wants to hold its shape. But it is elastic, and if we apply a force to it, it changes shape. The amount of change in its shape will be proportional to the force applied to it. That's Hooke's law of elasticity. Nothing could be simpler. How does that apply? Jump with me and we'll see. By attaching a pointer or dial to a spring in a particular way, we can use the "coefficient of elasticity" of the spring to tell us how much gravity is pulling on something (which is force). We use that something to change the shape of the spring, and by indexing the movement of that spring, that is, setting up a scale or dial, we can use the device (after calibration) to give us a fairly accurate measure of the weight of an object. Most of us are familiar with the spring scale as the so-call "bathroom scale" which is kept secreted away in the water closet. It's a spring scale, and a useful device (though there seem to be more and more electronic interlopers). There are also small versions of the spring scale, too. We find them in home kitchens for weighing food or small objects, as well as in some fishing tackle boxes. Before the electronic age, these little scales were everywhere that there was commerce. Think of all the stuff that gets weighed from meat and produce at the store to the letters and packages at the mailing places. The spring scale used to do all that. And it did it pretty well, too. Links are provided to Wikipedia articles for further reading. A device used to determine the weight of an object (usually fairly light like 10 pounds or less). It uses a spring attached to a hook to work. The object to be weighed is hung from the hook, which compresses the spring. The amount that the spring is compressed is read on a scale that is graduated in pounds.
How do you measure mass using a triple beam balance?
Because it is a weight measuring instrument which is able to measure weights to an accuracy of about 5 to 10 gram. Spring Balances which are commonly for cooking measures,are not very sensitive or accurate. You can only get an accuracy within about 20 grams with spring balances.
What is the Difference between net weight and net net weight?
Unit net weight Weight (mass) of goods including any packing normally going with them to a buyer in a retail sale. Net net weight Weight (mass) of the goods themselves without any packing.
What is oscillation of a spring?
The oscillation of a spring is the motion that the spring makes when disturbed. Imagine holding the end of a spring and hanging a weight to the other end. If you do not disturb the weight, it will stay in a static position. However, when you pull down on the weight and let go, the spring "oscillates" up and down. The spring could also be compressed and released, creating the same effect. The up and down motion, which has a specific velocity and period relating to the spring constant k, is oscillation.
How can we calculate the weight of iron plates?
If actually weighing the plates is impractical, you could try hanging the plates from a spring, and testing to find the spring's k value, and recording the displacement of the object while hanging from the spring, and use that to calculate the force on the plate, which equals mg. if the density is known, you could immerse the plates in something to find their volume and then calculate their weight from that. or, you could try and pull them with a force meter, taking two data points so that you can solve for the both the friction coefficient and weight.
How is clock tower movement possible without electricity?
The source of energy is the hanging weight(s) in the tower....or a wound spring if a more modern mechanism is used. Think of a Grandfather Clock. It is "wound" by pulling on a chain which raises the hanging weight(s) in the body of the clock. The force of gravity pulling on the weights provides the energy to run the clock. Note however, that you actually input the energy initially, when you pulled on the chain to raise the weight. That rise increased the weight's Potential Energy, which is then slowly converted back to Kinetic Energy as the weight slowly is lowered by the Clockwork mechanism.
How is the spring rate measured on a vehicle?
By how much weight it takes to compress the spring over a given distance. But without taking the spring out of the car, I'm not sure sorry. A good question though.
How much ounces does a half of meat have?
A side of beef (1/2 beef) is sold by the hanging weight. Hanging weight is the weight of the side before it is trimmed and cut. The typical approximate hanging weight of a side of beef is 300 lbs = 4,800 ounces.
What enables a pendulum to swing back and forth in a grandfather clock?
Spring Tension or a hanging weight. They are geared up to a small special shaped cog that applies pressure to the pendulem intermittantly.
If a 30kg weight is hanging on a spring and it stretches 0.5m what is the spring constant of the spring?
Hooks law: F=-x*K F=Force x=distance = 0.5m K=constant F=mass*9.81 = 30*9.81=aaaa [N] aaa = -0.5 * K => K = something
A metallic weight is suspended from a metal spring. If now a current is passed through the spring which will happen?
With the information given, the spring will contract and lift the weight.
What is the relationship between the extension of the spring and the weight hung on it?
when the extension of the spring increases the weight hung on it also increases
What is the defienition of apparent weight?
The weight as measured by a spring balance (registers weight by how far a spring is stretched). If the article is in water, etc, the registered weight will be less than the article's true weight.
How much weight can a hanging storage organizer handle?
It depends on what kind of organizer you are hanging. For example, a garage hanging storage organizer can hold up to 250 pounds. However, a closet organizer for clothing can hold much less weight.
What is a spring meter?
A spring meter is a meter that measures weight. It is a type of scale which uses a spring.
