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.
Let us take a look at how one of these scholars or critics goes about his work. Let’s say he is going to write a commentary on a particular painting. If he is not a man of intuition, certain features will characterize his approach. First he will try to place the painting genealogically, or he will try to define the painting by assigning it to a particular school. He feels uneasy unless he succeeds in doing this.
But more than anything, he is extremely wordy. He seems incapable of speaking of beauty without innumerable layers of adjectives.
One can study an object and note its features, but that only touches the surface. A knowledge of an artwork’s properties does not lead to an understanding of its essence.
