In measuring blockwall quantity, are quantities for lintel beams and attached columns computed separately?

are you looking for a block count? if so then yes
976475
height by width measured in feet

Determining the mass is trivial: just weigh the block.  For the density, you will need to know the volume, which will require some measuring with a ruler.  Then divide the mass by the volume for your answer.

If you are in the US, there is a building codebook that has tables for all wire sizes and their ratings.  Its called the NEC handbook

it is quite an inexact calculation, here are a few attempts\n\nhttp://hypertextbook.com/facts/2006/KristineMcPherson.shtml

Try buying a copy, try a local structural design firm, try a local engineering school, try a local library.\n\nIf you know enough to use the load factors, you should know enough to find them.

The ultimate strength of a beam is found by US = max load/CSA.  There's not a lot of math to it, but you do need to measure pretty carefully.\n\nThere comes a problem, however, where some materials "stretch" before actually failing, thus making the measurement of the max load difficult.  As an example, if you've ever pulled plastic wrap apart, it gets easier at a point right before it breaks into two.  The point where after you pull on it and it gets easier is called the yield strength.  After you pass the yield strength, you don't need as much force to cause failure in the material.\n\nNow in steel, the yield and ultimate strengths are pretty close to each other that the above discussion really doesn't affect it if you are trying to break a beam on your own.  But the ultimate strength of steel is probably something you can look up in a table somewhere.  Then you can use the above formula to see how much your beam can take based on the US and the cross sectional area.

It's called civil engineering design. Most of these things are designed by the engineer as needed, based on the size of what they are putting in. Sorry, but you probably won't find any cookie cutter designs floating on the internet. Some design companies may have them internally.

a city block is not a standard unit of measurement, so your question cannot be answered accurately.

I sense a tweak here. Answer 2 provides only two dimensions and quotes an unfindable site (alldimesions.org; also can't find alldimensions.org (re-spelled) or all-dimensions.org (hyphenated)). Nor any reference to a log foot or log-foot, except in a web site that sells log foot-bridges (ref.).\nGoogle "lumber log foot" and you will find plenty of references to estimating the board-feet in a given sized log, but no log foot. By a secret and powerful process of induction, I therefore conclude that a log foot is 12 cubits by 8 furlongs by 3 angstrom units.

A lintol or lintel is a means of supporting something above.\nA window opening or door opening for example within a brick wall will have some means of supporting the brickwork above the opening.\nLintols could be made out of timber, steel, concrete or bricks. However where the timber, steel or concrete lintols\nwould mostly be made in one piece and generally be horizontal, a brick lintol would have to be constructed in an arch form and with a temporary support (formwork or falsework) and with a "key" brick placed at the top of the arch similar to what you might see in an old stone arch which would have the "key"stone almost wedge shape.

An engineer, would require the weight "per foot" of the beams, and the number and location of support locations under each beam.\n \nFirst is to calculate the "dead load" and "deflection" of beams.\n\nSecond, afterwards one may calculate the live load and prescribe its bearing upon beams....\n\nIt's all in the details, the details, the details...\n\nThis is the best I can do , with what information you presented...

You need to measure the outside walls, not the square footage. Vinyl siding is measured in running feet, not square feet. Measure the length of each of your outside walls, than measure the height of the walls, and include the gabels if your putting siding there, this is very important, especially if you have a split level home. Take these measurements with you to the Home Depot, Sears wherever your buying the siding.

that's a real vague question, try to be more specific or at least say what king of structure do u want? (steel, conc, ..?)\nanyways this is an exremely simple example.\n\nlets' say u want to design a tension member -carrying tension force = 100 tons, -between 2 supports and this member is a steel member of yield stress= 1.4\nso to get the area u need :\n100/1.4= 71.43 cm square let's say again u want it to be I-shaped steel then u'll need  I number 400 i.e IPE 400
