  2. Cylinder - Wikipedia

    en.wikipedia.org/wiki/Cylinder

    A cylindric section is the intersection of a cylinder's surface with a plane. They are, in general, curves and are special types of plane sections. The cylindric section by a plane that contains two elements of a cylinder is a parallelogram. [4] Such a cylindric section of a right cylinder is a rectangle. [4]

  3. Cylindrical lens - Wikipedia

    en.wikipedia.org/wiki/Cylindrical_lens

    Cylindrical lenses. A cylindrical lens is a lens which focuses light into a line instead of a point as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to intersection of the surface of the lens and a plane tangent to it along the cylinder's axis.

  4. Component parts of internal combustion engines - Wikipedia

    en.wikipedia.org/wiki/Component_parts_of...

    An illustration of several key components in a typical four-stroke engine. For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.

  5. Montessori sensorial materials - Wikipedia

    en.wikipedia.org/wiki/Montessori_sensorial_materials

    Green cylinders that vary in height and width. The shortest cylinder is the thickest and the tallest cylinder is the thinnest. The child can do a variety of exercises with these materials, including matching them with the cylinder blocks, stacking them on top of each other to form a tower, and arranging them in size or different patterns.

  6. Single- and double-acting cylinders - Wikipedia

    en.wikipedia.org/wiki/Single-_and_double-acting...

    Single-acting. A single-acting cylinder in a reciprocating engine is a cylinder in which the working fluid acts on one side of the piston only. A single-acting cylinder relies on the load, springs, other cylinders, or the momentum of a flywheel, to push the piston back in the other direction. Single-acting cylinders are found in most kinds of ...

  7. Cylinder head - Wikipedia

    en.wikipedia.org/wiki/Cylinder_head

    Cylinder head. In a piston engine, the cylinder head (aka " head ") sits above the cylinders, [1] forming the roof of the combustion chamber. In sidevalve engines the head is a simple plate of metal containing the spark plugs and possibly heat dissipation fins. In more modern overhead valve and overhead camshaft engines, the head is a more ...

  8. Cylinder (engine) - Wikipedia

    en.wikipedia.org/wiki/Cylinder_(engine)

    The cylinder is the space through which the piston travels, propelled by the energy generated from the combustion of the air/fuel mixture in the combustion chamber. [2] In an air-cooled engine, the walls of the cylinders are exposed to the airflow, to provide the primary method of cooling to the engine. Most air-cooled engines have cooling fins ...

  9. Graduated cylinder - Wikipedia

    en.wikipedia.org/wiki/Graduated_cylinder

    Graduated cylinder. A graduated cylinder, also known as a measuring cylinder or mixing cylinder, is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured.
