What Type of MATH is used in Blueprints?

Well, they don't stay at depth. They enter a submersible while at depth that is pressurized at the same depth. That is then taken up to the ship the rest of the crew is on, and the pressure is maintained throughout. If they somehow lost pressure in there, they would die a very painful death..

That's why I said "For instance"...
I've been in construction all my life and read blueprints, build buildings, etc. The plans one reads to build anything, requires math skills.

Vector, raster and topology

I don't know man, I met some pretty stupid people in my time that are supposed to be smart fellas.. The only math you really need to read or interpret plans is how to use a scale or tape measure. Geometry would help as well. Putting together a set of plans is a completely different monster.

You're going to have to have the scale of the drawing, is it going to be 1/4" = 12" or ?

Yes there will be some angles that have to be read as well.

Keep in mind that it's the construction crew reading what you call blueprints; there's not going to be any trig or calculus ON the drawings. The higher math calculations have been done by others.

You don't need math to read blueprints, they wete drawn so the simple minded mexican construction worker could look at it and build it.

The engineers who designed the oil platform have to take math up to cal3, linear algebra, statistics, statics, and dynamics.

A blueprint is a reproduction of a technical drawing, documenting an architecture or an engineering design, using a contact print process on light-sensitive sheets.

Traditional blueprints have largely been replaced by more modern, less expensive printing methods and digital displays. In the early 1940s, cyanotype blueprint began to be supplanted by diazo prints, also known as whiteprints, which have blue lines on a white background; thus these drawings are also called blue-lines or bluelines.

SO, what you really need to know is how TECHNICAL DRAWINGS are created.
[link to en.wikipedia.org (secure)]

and I cannot think of any particular "types of math" is used.

A technical drawing is an accurate and extensive specification with extensive MEASUREMENTS that allow skilled persons to BUILD or create.

It depend on where you are in the world most use the metric system while others use the Imperial system . At my work i build for temples and buildings all over the world so i use both systems just depends on what country drew the blueprints . Now if you are drawing blueprints thats a whole lot more complicated . Lots of math in the engineering and also the design aspects

THAT is what I'm getting at, thank you!
So the guys reading the plans & implementing them don't have to know any higher math?

THANKS, EVERYONE.

I know what I needed now, and I reeeeally appreciate it!
Wish I could buy you all a round of drinks!

Mainly Trigonometry. You don't need any more than that.

With a ruler, an 1/8 inch = one foot

Scale

Start there.

It will be on the plans and called out.

From there, it's pretty simple... unless you find yourself working on a platform

Trust me, the engineers do not leave the math up to the construction guys. If they did they'd be falling down left and right. About all a contractor needs to know when reading a plan is scale and the ability to measure.

geometry and physics

Geometry and trigonometry
Calculation of area

First of all, "blueprint" is an obsolete term.
Printers connected to computers print ANY color.
Units of dimensioning are the same ones used in any industry on the planet, METRIC or ENGLISH, now usually BOTH.

Go to a good local community college and enroll in the pre-engineering curriculum. Be sure and take "statics" and "dynamics", gear your classes towards the "petro-chemical" industry.

If you just want a job in that industry FORGET ABOUT IT.
The oil reserves are so high now, they may start giving cars away JUST to boost gasoline sales.

I install HVAC.

After 20+ years in the trade I was put on a new Federal prison job, and all the prints were metric.

I had to buy a metric ruler and tape measure.

I was mad at first, but later I thought of it as a learning experience and had fun with it.

It's cool to learn something new. But it sucks being forced to learn something new.

1/4" = 1' dammit, lol.

algebra trig and calculus

Scale is the most important one for the end user ( construction type worker). In almost 100 % of cases, the scale is described right on the drawings and even sometimes, a ruler or sample scale provided somewhere on the documents( think of a map - same concept). A group of drawings may have many different scales, so each page must be checked carefully. That and the ability to convert metric to imperial when required. other than that, calculations have been done at the design/engineering phase, usually aided by computers.

Fortran is actually really easy. You wait until late the night before the assignment is due, go to the computer lab, dive in the dumpster to see the printouts that all the other students did that had errors, find one with a really easy error to fix and fix it. There, not hard at all

She's right on the money. It's mostly Algebra, Geometry and Trig, though. The "fancy" math is all done in the final analysis. Vector calc and vector algebra makes an appearance here and there.

Why do you want to know?

It's for a writing project, as mentioned earlier in the thread.
I don't have to be able to read the blueprints, just needed accurate info for what I'm writing.

Thanks for all the help!

Larry, I can't respond to pvt msgs because I'm not a paid acct. It's a non-fiction about a high school grad who supervised a multi-national fab yard, building off-shore oil rig platforms in the 70s.
As a genetically-cursed maths idiot, I simply had no CLUE what type of skill it took to use a blueprint for such an undertaking.

Geometry, and geometrical tolerancing.

Would be helpful to know what information op is trying to gain from the blueprint.

Trig,

mainly

Never mind- this was answered- just didn't read far enough!!
