Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
"Every website that’s made me oooo and aaahhh lately has been of a special kind; they’re written and designed like essays. There’s an argument, a playfulness in the way that they’re not so much selling me something as they are trying to convince me of the thing. They use words and type and color in a way that makes me sit up and listen.
And I think that framing our work in this way lets us web designers explore exciting new possibilities. Instead of throwing a big carousel on the page and being done with it, thinking about making a website like an essay encourages us to focus on the tough questions. We need an introduction, we need to provide evidence for our statements, we need a conclusion, etc. This way we don’t have to get so caught up in the same old patterns that we’ve tried again and again in our work.
And by treating web design like an essay, we can be weird with the design. We can establish a distinct voice and make it sound like an honest-to-goodness human being wrote it, too."
