in this design, one or more lines holds many kites in an arch: a rotary two-anchor rainbow arch and/or a static two-anchor rainbow arch. If the kites making up the arch kite rotate using the Magnus effect the term also applied is rainbow kite or just bow kite or kite bow or "sky bow" or SkyBow; one form of the rotating arch or rainbow kite is ...
A suction caisson can effectively be described as an inverted bucket that is embedded in the marine sediment.Attachment to the sea bed is achieved either through pushing or by creating a negative pressure inside the caisson skirt by pumping water out of the caisson; both of these techniques have the effect of securing the caisson into the sea bed.
Slides are also sub-classified by the form of the surface(s) or shear zone(s) on which movement happens. The planes may be broadly parallel to the surface ("planar slides") or spoon-shaped ("rotational slides"). Slides can occur catastrophically, but movement on the surface can also be gradual and progressive.
An extension ladder. A ladder is a vertical or inclined set of rungs or steps commonly 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.
Some climbers will use a single full-thickness climbing rope with a diameter of approximately 9 to 11 mm (0.35 to 0.43 in), and some will use double ropes, or "half-ropes", to reduce rope drag (e.g. one rope is clipped into any given anchor or protection point), which have a reduced thickness of approximately 8 to 9 mm (0.31 to 0.35 in) to ...
The lever "anchor" pallet locks the larger wheel; when this is unlocked, a pallet on the end of the lever is given an impulse by the smaller wheel through the lever fork. The return stroke is "dead", with the anchor pallets serving only to lock and unlock, impulse being given in one direction through the single lever pallet.
