# Electrical Engineering/Model Railroads with Different Geometrical Shapes.

Question
QUESTION: Dear Prof Cleggsan

http://en.wikipedia.org/wiki/List_of_geometric_shapes
http://en.wikipedia.org/wiki/Toy

Straight line segments
----------------------

http://en.wikipedia.org/wiki/Cyclic_polygon
http://en.wikipedia.org/wiki/Balbis
http://en.wikipedia.org/wiki/Pentagon
http://en.wikipedia.org/wiki/Octagon

Curved

http://en.wikipedia.org/wiki/Ellipse
http://en.wikipedia.org/wiki/Reuleaux_triangle
http://en.wikipedia.org/wiki/Sphere
http://en.wikipedia.org/wiki/Pentagram

Not composed of circular arcs

http://en.wikipedia.org/wiki/Archimedean_spiral
http://en.wikipedia.org/wiki/Astroid
http://en.wikipedia.org/wiki/Super_ellipse
http://en.wikipedia.org/wiki/Tomahawk_(geometric_shape)

Do you feel by using different types of Geometrical Shapes viz Ellipse, Pentagon, Astroid etc can help in modeling different types of Railroads i.e. aid in actual construction of new rail routes,  rail tracks as well as help in constructing railroads toys for the same.

Thanks & Regards,

ANSWER: Well, every railroad has a path from point A to point B.  How that connection can be quantified is a matter of mapping and can use many forms whilst making its curvilinear pattern as it traverses its course.

There are also linear programming software that is used in constructing multi-connections across lines.

But train lines are more a function of elevations to traverse, community approval of the route and political sanctions.  Also, the line must serve the users best taking into account population centers, growth and trends.

Frankly, I can't see any need to include predetermined geometrics in the design of track layout.  Do you?

Interesting question.

Do you feel by using different types of Geometrical Shapes viz Ellipse, Pentagon, Astroid etc can help in modeling different types of Railroads i.e. aid in actual construction of new rail routes, rail tracks as well as help in constructing railroads toys for the same.

Also is it possible to design and develop new computer games and video games modeling new rail routes/tracks ?.

Questions
---------

1. Using DIFFERENT Geometrical Shapes to design and construct new rail routes / tracks. The answer is provided from your end. Thank you.

2. Using DIFFERENT Geometrical shapes for designing and constructing railroads toys.

3. Using DIFFERENT Geometrical shapes for designing and constructing new computer games modeling new rail routes/tracks similar to Solitaire, Hearts, Internet Checkers etc

4. Using DIFFERENT Geometrical Shapes for designing and constructing new video games modeling new rail routes/tracks ?.

2. I do not understand the fascination with geometric shaping.  It is already employed when designers make toys.  Plastic parts in particular are injection molded using molding parts that utilize the very thing you are speaking of in preparing the design parameters that go to the model builders.  Every shape has a geometry and that geometry can be represented mathematically or by design drawings as the products are manufactured.

3.  Once again, shapes and sizes are already a significant part of the library of digital design elements that are employed in games and drawing layout.  Nothing novel or unique it seems.

Finally, I do not see anything unique or novel about employing shapes that can be pulled out of a digital database or library.  Designers can use many tools in the design and implementation of a product design.  Simple case in point is MS Paint. This program which has been around for years has built in capability to produce rectangular, round and oval shapes with only the movement of the mouse.  CAD software used in graphic design has been used by engineers for many years in preparing 3 dimensional products.

There are so many tools available for designers now that just about any geometrical shape imaginable can be called up and implemented into a project.

I will say, however, that geometrics can be an art field where the beauty of the object can be enhanced with judicial use of design patterns.

And, there is an engineering side to all this; for example, in the design of a bridge it must also meet weight distribution as well as be earthquake proof and shock proof when heavy loading results during adverse conditions.

Hope this helps.
