Springboard Software Games
A springboard or diving board is used for diving and is a board that is itself a spring, i.e. a linear flex-spring, of the cantilever type. Springboards are commonly fixed by a hinge at one end (so they can be flipped up when not in use), and the other end usually hangs over a swimming pool, with a point midway between the hinge and the end resting on an adjustable fulcrum. Springboard materials Modern springboards are made out of a single-piece extrusion of aircraft-grade aluminum. The Maxiflex Model B, the board used in all major competitive diving events, is made out of such aluminum, and is heat treated for a yield strength of . The slip-resistant surface of the board is created using an epoxy resin, finished with a laminate of flint silica and alumina in between the top coats of resin. This thermal-cured resin is aqua-colored to match the water of a clean pool. Adjustment of the spring constant The spring constant of a springboard is usually adjusted by way of a fulcru ...

60 Minutes II
''60 Minutes II'' (also known as ''60 Minutes Wednesday'' and ''60 Minutes'') is an American weekly primetime news magazine television program that was intended to replicate the "signature style, journalistic quality and integrity" of the original ''60 Minutes'' series. It was initially allocated the slot on CBS on Wednesdays, then it was later moved to Fridays at 8:00p.m. The original ''60 Minutes'' continued airing on Sunday nights throughout the run of ''60 Minutes II''. The first edition of ''60 Minutes II'' ran on January 13, 1999. Its final broadcast was on September 2, 2005. ''60 Minutes II'' was renamed ''60 Minutes'' by CBS for the fall of 2004. CBS News president Andrew Heyward stated at the time, "The Roman numeral II created some confusion on the part of the viewers and suggested a watered-down version." The show was later renamed ''60 Minutes Wednesday'' to differentiate it from the original ''60 Minutes'' Sunday edition, but reverted to its original title on July ...

Tetraplegia
Tetraplegia, also known as quadriplegia, is defined as the dysfunction or loss of motor and/or sensory function in the cervical area of the spinal cord. A loss of motor function can present as either weakness or paralysis leading to partial or total loss of function in the arms, legs, trunk, and pelvis. ( Paraplegia is similar but affects the thoracic, lumbar, and sacral segments of the spinal cord and arm function is retained.) The paralysis may be flaccid or spastic. A loss of sensory function can present as an impairment or complete inability to sense light touch, pressure, heat, pinprick/pain, and proprioception. In these types of spinal cord injury, it is common to have a loss of both sensation and motor control. Signs and symptoms Although the most obvious symptom is impairment of the limbs, functioning is also impaired in the trunk and pelvic organs. This can lead to loss or impairment of controlling bowel and bladder, sexual function, digestion, breathing and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington (state)
Washington, officially the State of Washington, is a U.S. state, state in the Pacific Northwest region of the United States. It is often referred to as Washington State to distinguish it from Washington, D.C., the national capital, both named after George Washington (the first President of the United States, U.S. president). Washington borders the Pacific Ocean to the west, Oregon to the south, Idaho to the east, and shares Canada–United States border, an international border with the Provinces and territories of Canada, Canadian province of British Columbia to the north. Olympia, Washington, Olympia is the List of capitals in the United States, state capital, and the most populous city is Seattle. Washington is the List of U.S. states and territories by area, 18th-largest state, with an area of , and the List of U.S. states and territories by population, 13th-most populous state, with a population of just less than 8 million.

Norman Rockwell
Norman Percevel Rockwell (February 3, 1894 – November 8, 1978) was an American painter and illustrator. His works have a broad popular appeal in the United States for their reflection of Culture of the United States, the country's culture. Rockwell is most famous for the cover illustrations of everyday life he created for ''The Saturday Evening Post'' magazine over nearly five decades. Among the best-known of Rockwell's works are the ''Willie Gillis'' series, ''Rosie the Riveter#Saturday Evening Post, Rosie the Riveter'', the ''Four Freedoms (Norman Rockwell), Four Freedoms'' series, ''Saying Grace (Rockwell), Saying Grace'', and ''The Problem We All Live With''.

These works include popular images that reflect the Scout Promise, Scout Oath and ''Scout Law'' such as ''The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lever
A lever is a simple machine consisting of a beam (structure), beam or rigid rod pivoted at a fixed hinge, or '':wikt:fulcrum, fulcrum''. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load, and effort, the lever is divided into Lever#Types of levers, three types. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage, which is mechanical advantage gained in the system, equal to the ratio of the output force to the input force. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English language, English around 1300 from . This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to , itself from the adjective ''levis'', meaning "light" (as in "not heavy"). The word's primary origin is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest Chord (geometry), chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length d of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius r. :d = 2r \qquad\text\qquad r = \frac. The word "diameter" is derived from (), "diameter of a circle", from (), "across, through" and (), "measure". It is often abbreviated \text, \text, d, or \varnothing. Constructions With straightedge and compass, a diameter of a given circle can be constructed as the perpendicular bisector of an arbitrary chord. Drawing two diameters in this way can be used to locate the center of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ratio
In mathematics, a ratio () shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). Similarly, the ratio of lemons to oranges is 6:8 (or 3:4) and the ratio of oranges to the total amount of fruit is 8:14 (or 4:7). The numbers in a ratio may be quantities of any kind, such as counts of people or objects, or such as measurements of lengths, weights, time, etc. In most contexts, both numbers are restricted to be Positive integer, positive. A ratio may be specified either by giving both constituting numbers, written as "''a'' to ''b''" or "''a'':''b''", or by giving just the value of their quotient Equal quotients correspond to equal ratios. A statement expressing the equality of two ratios is called a ''proportion''. Consequently, a ratio may be considered as an ordered pair of numbers, a Fraction (mathematic ...

Resonance
Resonance is a phenomenon that occurs when an object or system is subjected to an external force or vibration whose frequency matches a resonant frequency (or resonance frequency) of the system, defined as a frequency that generates a maximum amplitude response in the system. When this happens, the object or system absorbs energy from the external force and starts vibrating with a larger amplitude. Resonance can occur in various systems, such as mechanical, electrical, or acoustic systems, and it is often desirable in certain applications, such as musical instruments or radio receivers. However, resonance can also be detrimental, leading to excessive vibrations or even structural failure in some cases. All systems, including molecular systems and particles, tend to vibrate at a natural frequency depending upon their structure; when there is very little damping this frequency is approximately equal to, but slightly above, the resonant frequency. When an Oscillation, oscillat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
