The strength of ships is a topic of key interest to naval architects and shipbuilders. Ships which are built too strong are heavy, slow, and cost extra money to build and operate since they weigh more, whilst ships which are built too weakly suffer from minor hull damage and in some extreme cases catastrophic failure and sinking.
Most passenger vehicles and some freight vehicles will have a bulkhead which separates the engine compartment from the passenger compartment or cab; [11] the automotive use is analogous to the nautical term in that the bulkhead is an internal wall which separates different parts of the vehicle. Some passenger vehicles (particularly sedan/saloon ...
Hogging is the stress a ship's hull or keel experiences that causes the center or the keel to bend upward. Sagging is the stress a ship's hull or keel is placed under when a wave is the same length as the ship and the ship is in the trough of two waves.
A car chassis will be different from one for commercial vehicles because of the heavier loads and constant work use. [5] Commercial vehicle manufacturers sell "chassis only", "cowl and chassis", as well as "chassis cab" versions that can be outfitted with specialized bodies. These include motor homes, fire engines, ambulances, box trucks, etc.
The hull, constructed of steel bulkheads and stringers with Duralumin skinning on the sides and bottom, but fabric on parts of the upper decking, housed the crew in a cockpit near the nose, who were protected by a raised coaming. The engines and fuel lines were also housed inside the hull; they could be serviced in flight by a mechanic. [1]
Marine automobile engines are types of automobile petrol-or diesel engines that have been specifically modified for use in the marine environment. The differences include changes made for the operating in a marine environment, safety, performance, and for regulatory [1] requirements. The act of modifying is called 'marinisation'.
A strongback is a beam or girder which acts as a secondary support member to an existing structure. A strongback in a staircase is usually ordinary two-by dimensional lumber attached to the staircase stringers to stiffen the assembly.
These are openwork girder structures built up from steel or iron bars which are usually 4–7 in (100–180 mm) thick, welded into a single load-bearing assembly. They were first used on the Bury Bar Frame locomotive during the 1830s, and were widely used in nineteenth century American locomotives (including those exported to Australia and New ...
