cylinders
Cans without ends
Cylinders are three-dimensional shapes with parallel circular ends connected by a curved surface—like a can or a pipe.
In engines, cylinders are the chambers where pistons move up and down: a four-cylinder engine, The car was only firing on three cylinders.
That mechanical sense extends figuratively—to operate on all cylinders is to perform at full capacity.
