No. Weight is the force that a mass pushes down with due to gravity or acceleration. Please do not redefine words that already have well established definitions.
No, weight is not a force. Weight is a man made measurement for the force of atmospheric pressure upon any dense matter.
Weight does not exist unless you can scale measure dense mass resisting atmospheric pressure.
If that was true, then weight would change with changes in atmospheric pressure. Would you care to show us an example of an object's weight changing with a change in atmospheric pressure?
Engineers use gravity in their calculations. To be a little more precise, engineers use gravity to calculate the weight loads of structures.
So tell me how they manage this. What do they actually use as a tool do do this?
For most calculations, they use the generally accepted value of 9.8 m/s
2. Why measure something that has already been measured countless times before?
I'm not sure that I understand what you're getting at. Why would engineers test materials inside a vacuum chamber if it isn't designed to work in a vacuum?
I don't know. I keep getting told that all this gravity crap is tested inside a vacuum, so you tell me.
Still not sure what you're getting at. Some gravimeters will time how long it takes for an object to fall in a vacuum. Is that what you're talking about?
First of all, I never claimed to know everything about everything. However, I have taken enough physics and technical mechanics courses to have a vague idea of what I'm talking about.
It appears that you seem to think you do because you enter into any and every topic no matter what. You're either a natural worldly super genius or you simply look up whatever you feel you want to argue.
Which is it?
First of all, no, I don't go into "any and every topic no matter what". I've gotten much more selective as to which discussions I get into.
Secondly, what's wrong with looking stuff up on the internet? Sharing information is pretty much the reason that the internet was invented. Don't forget that the world wide web was invented by a computer engineer at CERN in order to share their data.
And yes, I do believe that there is nothing like good argument once in a while. Sadly, this thread is nothing like a good argument.
Physically calculate? I'm not sure, but that sounds like a contradiction in terms. Materials engineers have various ways of testing various properties of materials, including strength and density. Engineers will use the density and volume of a material, along with the average value of 9.8 m/s2, to calculate the weight of a structure.
How exactly do they achieve this. They must use a tool/s, so what and how do they do this?
How does anyone measure anything? I would think that the primary tools would be a pencil and paper. Or, more likely, a decent CAD program used in designing every component of the structure.
Well, I suppose that depends on what sort of engineer you're talking about. A gravimeter is a fairly specific tool that not many engineers would actually use.
A fairly specific tool? It's a gravimeter that apparently engineers use for buildings and bridges and such, isn't it?
So tell me how it works.
Let's say Joe Bloggs is about to build a sky scraper. He arrives on site and starts his test for gravity forces. Tell me from this point what happens?
If you can't then can any of your global friends?
Joe Bloggs doesn't need to go on site to test for gravity forces to build his skyscraper. He just uses the already established value of 9.8 m/s
2, which has not been shown to vary significantly anywhere around the world.
However, fields like natural resource surveyors have been known to use gravimeters to map the variations in density below the earth's surface to look for various things like oil and gas.
Well we'll leave this bit for now. Let's concentrate on above ground where we can all see what's going on....hopefully.
Why? Being able to use gravity to help find valuable natural resources deep underground sounds quite handy to me.
