Entasis is a design principle used in architecture to counteract the optical illusion that straight lines appear to sag in the middle. It involves subtly curving or tapering the vertical columns of a building so that they appear straight to the eye. This technique creates a more visually pleasing and stable appearance in classical architecture.
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
the work a machine does is the work output what it takes to do the work is the work input
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
Entasis - company - was created in 1996.
A convex curve in the shaft of a column
"Entasis" refers to the taper of a column.
They did that through entasis, creating an optical illusion. Normally the columns would seem to become narrower higher up when you were looking up at them. Entasis, a little bulging out in the middle of the column segments made the column appear straight and of uniform width.
To fool the eye against them appearing narrower as they rise
It had to do with the apparent convergence of paralell lines- which can even be photographed taken at long focus down a railroad track- check for traffic first! The illusion is that the lines converge in the distance, the reality is they are at precise track gauge of 4 Foot 8 I/2 inches. this illusion, like many, can be photographed, there is something similar with columns on building sites, it is discussed in some detail in ione of the books on Atlantis by a man named, oddly Stacy-Judd , no relation to the Russian princess! Stacy_Judd had an architectural background, maybe in art school and explains how it worked- it was called entasis. read the book, that can explain it better than I, who twice went to summer school for math. +++ Bit of tangle, that lot! The apparent effect of narrowing with distance is called "Perspective". Entasis was used by the Ancient Greeks in their buildings, by thickening vertical columns very slightly in the middle. If a column is parallel it looks as if waisted-in. The entasis has to be calculated very carefully to avoid the reverse effect, which can end up looking very silly!.
