Stair Riser
Stairs are a structure designed to bridge a large vertical distance between lower and higher levels by dividing it into smaller vertical distances. This is achieved as a diagonal series of horizontal platforms called steps which enable passage to the other level by stepping from one to another step in turn. Steps are very typically rectangular. Stairs may be straight, round, or may consist of two or more straight pieces connected at angles. Types of stairs include staircases (also called stairways), ladders, and escalators. Some alternatives to stairs are elevators (also called lifts), stairlifts, inclined moving walkways, and ramps. A stairwell is a vertical shaft or opening that contains a staircase. A flight (of stairs) is an inclined part of a staircase consisting of steps (and their lateral supports if supports are separate from steps). Components and terms A ''stair'', or a ''stairstep'', is one step in a flight of stairs.R.E. Putnam and G.E. Carlson, ''Architectural a ...

Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag or, in a ram-air parachute, aerodynamic lift. A major application is to support people, for recreation or as a safety device for aviators, who can exit from an aircraft at height and descend safely to earth. A parachute is usually made of a light, strong fabric. Early parachutes were made of silk. The most common fabric today is nylon. A parachute's canopy is typically dome-shaped, but some are rectangles, inverted domes, and other shapes. A variety of loads are attached to parachutes, including people, food, equipment, space capsules, and bombs. History Middle Ages In 852, in Córdoba, Spain, the Moorish man Armen Firman attempted unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent great injury when he reached the ground." Early Renaissance The earliest evidence f ...

Waking Up Early
Waking up early is rising before most others and has also been described as a productivity method - rising early and consistently so as to be able to accomplish more during the day. This method has been recommended since antiquity and is now recommended by a number of personal development gurus. Commentary Within the context of religious observances, spiritual writers have called this practice "the heroic minute", referring to the sacrifice which this entails. The philosopher Aristotle wrote in his ''Economics'' that "Rising before daylight is also to be commended; it is a healthy habit, and gives more time for the management of the household as well as for liberal studies." Benjamin Franklin is quoted to have said: "Early to bed and early to rise, makes a man healthy, wealthy, and wise". It is a saying that is viewed as a commonsensical proverb, which was included in "A Method of Prayer" by Mathew Henry who also listed it as a phrase "long said." Franklin is also quoted ...

Terrace (geology)
In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp". The tread and the steeper descending slope (riser or scarp) together constitute the terrace. Terraces can also consist of a tread bounded on all sides by a descending riser or scarp. A narrow terrace is often called a bench.Howard, A.D., R.W. Fairbridge, J.H. Quinn, 1968, "Terraces, Fluvial—Introduction", in R.W. Fairbridge, ed., ''The Encyclopedia of Geomorphology: Encyclopedia of Earth Science Series'', vol. 3. Reinhold Book Corporation. New York, New York.Jackson, J.A., 1997, ''Glossary of Geology''. American Geological Institute. Alexandria, Virginia. The sediments underlying the tread and riser of a terrace are also commonly, but incorrectly, called terraces, leading to confusion. Terraces are formed in various ways. Fluvial terraces ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Riser (casting)
A riser, also known as a feeder, is a reservoir built into a metal casting mold to prevent cavities due to shrinkage. Most metals are less dense as a liquid than as a solid so castings shrink upon cooling, which can leave a void at the last point to solidify. Risers prevent this by providing molten metal to the casting as it solidifies, so that the cavity forms in the riser and not the casting.. Risers are not effective on materials that have a large freezing range, because directional solidification is not possible. They are also not needed for casting processes that utilized pressure to fill the mold cavity. Theory Risers are only effective if three conditions are met: the riser cools after the casting, the riser has enough material to compensate for the casting shrinkage, and the casting directionally solidifies towards the riser. For the riser to cool after the casting the riser must cool more slowly than the casting. Chvorinov's rule briefly states that the slowest cooling ...

Recurve Bow
In archery, a recurve bow is one of the main shapes a bow can take, with limbs that curve away from the archer when unstrung. A recurve bow stores more energy and delivers energy more efficiently than the equivalent straight-limbed bow, giving a greater amount of energy and speed to the arrow. A recurve will permit a shorter bow than the simple straight limb bow for given arrow energy, and this form was often preferred by archers in environments where long weapons could be cumbersome, such as in brush and forest terrain, or while on horseback. Recurved limbs also put greater stress on the materials used to make the bow, and they may make more noise with the shot. Extreme recurves make the bow unstable when being strung. An unstrung recurve bow can have a confusing shape and many Native American weapons, when separated from their original owners and cultures, were incorrectly strung backwards and destroyed when attempts were made to shoot them. A test performed by Hepworth and S ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Theatre Platform
In theatre, a platform (also referred to as a riser or rostrum) is a stationary, standard flat walking surface for actors to perform on. Typically, they are built to be assembled modularly. They are often used to provide varying levels, to make a show more visually interesting. They are also used to separate areas on stage, and as seating bleachers. This is in contrast to scenery wagons, which are mobile platforms that are supported by casters instead of feet. Construction Platforms are composed of a frame, a lid, and legs. Lids Lids are typically made from a sheet of plywood, although oriented strand board is also sometimes used. Sometimes another layer is added on top of the plywood. Hardboard is sometimes used as an easily replaceable and sturdy cover. Homasote is sometimes used because it is quiet and more comfortable to walk on. Occasionally, a layer of muslin is added on top of these materials, as it takes paint better than other options. Framing Framing is most commonly m ...

Skateboard
A skateboard is a type of sports equipment used for skateboarding. They are usually made of a specially designed 7-8 ply maple plywood deck and polyurethane wheels attached to the underside by a pair of skateboarding trucks. The skateboarder moves by pushing with one foot while the other foot remains balanced on the board, or by pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by simply standing on the deck while on a downward slope and allowing gravity to propel the board and rider. If the rider's leading foot is their right foot, they are said to ride "goofy". The two main types of skateboards are the longboard and the shortboard. The shape of the board is also important: the skateboard must be concaved to perform tricks. History Skateboarding started in California in the 1950s. The first skateboards were made from roller skates attached to a board. Skateboarding gained in popularity because of surfing: in fact, skateboarding ...

Riser Card
A Riser Card is a printed circuit board that gives a computer motherboard the option for additional expansion cards to be added to the computer. Usage Risers is usually connected to the mainboard's slot through an edge connector, though some, such as NLX and Next Unit of Computing Extreme, have the edge connector on the mainboard instead and have the mainboard plug into Risers. In general, the main purpose is to change the orientation of the expansion cards such that they fit a limited space within casing. Riser Cables Riser Cables is an evolution of Riser Cards that utilized improved specifications (specifically the use of PCI Express) and better materials, which allows further distances of data transmission and orientation flexibility than traditional riser cards. These cables used a Riser Card PCB and an edge connector on each side of the cable, with a copper alloy surrounded by a plastic insulator that allows for the further data transmission distances. These cables are ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
