A limited-slip differential (LSD) is a type of differential gear train that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. Limited-slip differentials are often known by the generic trademark Positraction , a brand name owned by General Motors and originally used for its ...
With the option of fitting extra decks, large numbers of vehicles could be transported, and loaded into landing craft via ramps. Despite an initial specification for a speed of 17 knots (20 mph; 31 km/h), the LSDs were capable of only 15.6 knots (18.0 mph; 28.9 km/h).
A dock landing ship (also called landing ship, dock or LSD) is an amphibious warfare ship with a well dock to transport and launch landing craft and amphibious vehicles. [1] Some ships with well decks, such as the Soviet Ivan Rogov class , also have bow doors to enable them to deliver vehicles directly onto a beach (like a tank landing ship ).
An old and simple slipway for smaller boats, Ystad, Sweden In its simplest form, a slipway is a plain ramp, typically made of concrete, steel, stone or even wood.The height of the tide can limit the usability of a slip: unless the ramp continues well below the low water level it may not be usable at low tide.
Also unlike in many locales in urban Texas, where an exit ramp may actually precede the entrance ramp for the previous interchange to facilitate access to businesses situated directly on the frontage road (in effect, the two interchanges overlap along the frontage road), Michigan slip ramps to and from frontage roads are generally positioned as ...
Ingressing traffic is entering the highway via an on-ramp or entrance ramp, while egressing traffic is exiting the highway via an off-ramp or exit ramp. [11] Directional ramp A ramp that curves toward the desired direction of travel; i.e., a ramp that makes a left turn exits from the left side of the roadway (a left exit). [12] Semi-directional ...
Lake Shore Drive (officially Jean Baptiste Pointe du Sable Lake Shore Drive; [2] [3] also known as DuSable Lake Shore Drive, [4] the Outer Drive, [5] the Drive, LSD or DLSD) is a semi-limited access expressway that runs alongside the shoreline of Lake Michigan and its adjacent parkland and beaches in Chicago, Illinois.
Initially a linkspan was a ramp that was attached to the pier at one end and was suspended above the water at the other. The height above the water was controlled either by hydraulic rams or cables, these types of linkspans were less well designed for the various conditions of the tide, wave and current and so were superseded by underwater tank linkspans that through compressed air can be ...
