Ladder Golf, Homerville
A ladder is a vertical or inclined set of rungs or steps used for climbing or descending. There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such as those made of rope or aluminium, that may be hung from the top. The vertical members of a rigid ladder are called stringers or rails (US) or stiles (UK). Rigid ladders are usually portable, but some types are permanently fixed to a structure, building, or equipment. They are commonly made of metal, wood, or fiberglass, but they have been known to be made of tough plastic. Historical usages Ladders are ancient tools and technology. A ladder is featured in a Mesolithic rock painting that is at least 10,000 years old, depicted in the Spider Caves in Valencia, Spain. The painting depicts two humans using a ladder to reach a wild honeybee nest to harvest honey. The ladder is depicted as long and flexible, possibly made out of some sort of gr ...

Underwater Diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving, an ambiguous term with several possible meanings, depending on context. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well-adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold (freediving) or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives ...

Hinge
A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other Translation (geometry), translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of Flexure bearing, flexible material or of moving components. In biology, many joints function as hinges, like the elbow joint. History Ancient remains of stone, marble, wood, and bronze hinges have been found. Some date back to at least Ancient Egypt. In Ancient Rome, hinges were called wikt:cardo#Latin, cardō and gave name to the goddess Cardea and the main street Cardo. This name cardō lives on figuratively today as "the chief thing (on which something turns or depends)" in words such as ''wikt:cardinal#English, cardinal''. According to the OED, the English word hinge is related to ''wikt:hang#English, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Roof
A roof ( : roofs or rooves) is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind. A roof is part of the building envelope. The characteristics of a roof are dependent upon the purpose of the building that it covers, the available roofing materials and the local traditions of construction and wider concepts of architectural design and practice, and may also be governed by local or national legislation. In most countries, a roof protects primarily against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of a garden conservatory protects plants from cold, wind, and rain, but admits light. A roof may also provide additional living space, for example, a roof garden. Etymology Old English 'roof, ceiling, top, summit; heaven, sky', also f ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fruit Picking
Fruit picking or fruit harvesting is a seasonal activity (paid or recreational) that occurs during harvest time in areas with fruit growing wild or being farmed in orchards. Some farms market "You-Pick" for orchards, such as the tradition of Apple picking in North America, as a form of value-add agritourism. Types of fruit Apple picking Apple picking is an activity found at apple farms. Apple orchards may be opened to the public, allowing consumers to pick their own apples or purchase pre-picked apples. Although this is ultimately a method of purchasing apples, it is often a social activity as well. Apple picking is often a very popular dating ritual in the American Midwest. Apple orchards catering to a family outing will provide additional activities beyond the picking of apples. Many have petting zoos, restaurants and country shops that sell related products such as home-made jams and jellies. This aspect of the activity is especially popular in the Northeastern United State ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pompier Ladder
A hook ladder, also known as a pompier ladder (from the French ''pompier'' meaning firefighter) is a type of ladder that can be attached to a window sill or similar ledge by the use of a hooked extending bill with serrations on the underside. The hooked ladder then hangs suspended vertically down the face of the building. The ladder was developed to access buildings via enclosed alleys, lightwells and yards to which other types of ladder could not be taken. A pair of men and two ladders could be used to scale a building to considerable heights, by climbing from floor to floor and taking the ladders up behind and pitching to the next floor. The original French design was a single beam ladder with pairs of rungs projected outward on both sides of the beam. The British version was a conventional two-string ash ladder around long and wide. Hook ladders can be used to scale from floor to floor on multi-storey buildings by way of exterior windows. The ladders hook onto the window led ...

Fixed Ladder
A fixed ladder is a vertical ladder mounted permanently to a structure. These ladders are primarily used to access roofs or other structures for industrial purposes. In the United States, these ladders are covered by OSHA and ANSI standards. Components Fixed ladders consist of the following components: *Rungs: all fixed ladders have rungs, dictated by OSHA Standar1910.27(b)(1)of no more than 12" (300 mm) on center (measured as the distance from the centerline of a rung to the center line of the next rung), and at 16" (410 mm) clear width. *Side members: These are the rails on the side of the ladder that are designed that the foot cannot slip off the end. Mostly flat bar or angle profile and sometimes channel. *Stand-off brackets: Dictated by OSHA Standar1910.27(c)(4)stand-off brackets must be at least 7" (180 mm) longer than the farthest obstruction for clearance on the back side of ladder. This means that if there is a 4" (100 mm) gutter projecting from the si ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pawl
A pawl is a movable lever that engages a fixed component to either prevent movement in one direction or restrain it altogether. As such, it is a type of latch and can also be considered a type of dog. It typically consists of a spring-loaded lever that engages a mating component at a steep enough angle to restrain it. Pawls are often tapered, being widened at their pivot for anchoring and narrow at their tip. Applications ;Anchor windlass: A pawl is used in an anchor windlass to prevent a free-spooling chain by grabbing and snubbing an individual link. Similar mechanisms include a Devil's claw, or a claw and dog. ;Ratchet: A pawl is used in combination with a ratchet gear in socket wrenches, bicycle freehubs, winches, and many other applications. ;Ladder: Dogs (in the form of pawls) are used on extension ladders to temporarily anchor their sections to one-another. ;Table saw: Pawls are used on table saws to prevent a workpiece being sawn from kicking back. ;Transmission: A ...
