Why are electricity transmission lines different shapes in different countries?

Why does there have to be a reason? Different basic shapes are required based on voltage, wind conditions and number of lines but beyond that it's just aesthetics.

Frick you.
some guy designed those towers. each guy who designed it may have had different requirements, but ultimately there are infinitely many designs that fit any set of constraints. it comes down to style and preference. if you had ever designed anything mechanical you would understand this, moron.
>any set of constraints
*any set of practically fulfillable constraints because I know underage sperglords like you latch on to every word of a statement
They are all trivial, what's there to expand?
Engineering is like programming, it isn’t binary right or wrong like mathematics.
As the other anon said, certain countries have certain conditions, temperature, the amount of energy, winds, position on the globe, etc that all factor in to what ways the problem can be solved, and even then obviously not everyone agrees on one method of solving any problem, so different people do different designs
Engineering like programming is binary anon, It works or it doesn't.
and when you have several working designs, what then?
No don't go thinking that far. Brain hurty
There might be a real valid reason that isnt being discussed. Maybe if they get the wrong shape it would explode.
everything started with a hasty picture on the back of an envelope
one country started with T, another started with Y or F
there's no real practical difference
some things are just the way they are because decision was made decades ago and the design is kept the same throughout the country just to keep things tidy and uniform and for ease of manufacturing/repair. You want to keep every part the same
Ever noticed PC numpad goes 7894561230 while phone numpad goes 1234567890?
Same thing, basically. Neither option is objectively better or worse. It's just a choice people settled on.
>Ever noticed PC numpad goes 7894561230 while phone numpad goes 1234567890?
Maybe different requirements. Phone was first and has * and # extra. PC is made for data. Zero has double size located to use your thumb for it (e.g. better stress distribution) .
first phones with that layout didn't have the extra two buttons at all
and first button phones imitated the rotating dial
I've seen some keypads with an extra column of keys marked A,B,C,D. They generate dual tones like the rest of the keypad. Something about system signaling.
I leave it up to your imagination what U and B stand for
It's because the keyboard is decendent from typewriters and calculators where it's like that while the phone is from the rotary phone which attempts to mimic a clock face.
Real answer is copyright.
physics, specifically statics differs from country to country, as it is subject to legislation.
