The Austral 20 is a 20 ft (6.1 m) long trailer sailer, designed and manufactured in Australia by Austral Yachts in Adelaide. [1] [2] The boats feature roller reefing jibs and slab reefing mains as standard. [3] The Austral 20 is a roomy and easy to sail design, for which Austral Yachts won a design award in 1979.
Amendment 2 of 2005 then also standardized 45 ft (13.7 m) length containers. [7] The maximum gross mass (MGM) rating of laden 20- and 30-foot length units was notably increased to 30,480 kg (67,200 lb) by Amendment 1 of 2005. [7] Until then, the MGM for 20- and 30-foot boxes was 24,000 kg (52,910 lb), and 25,400 kg (56,000 lb) respectively.
The RCH-155 module is very similar to the Artillery Gun Module (AGM, Artillerie-Geschütz-Modul), but has a lower profile. [3] The AGM was designed to have the firepower of the PzH 2000 in an air-portable package with the A400M aircraft this was possible when installed on an ASCOD-2 platform (known as the DONAR).
Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage).
The American Society of Civil Engineers (or ASCE) specified rail profiles in 1893 [20] for 5 lb/yd (2.5 kg/m) increments from 40 to 100 lb/yd (19.8 to 49.6 kg/m). Height of rail equaled width of foot for each ASCE tee-rail weight; and the profiles specified fixed proportion of weight in head, web and foot of 42%, 21% and 37%, respectively.
The I-20 is a modernized version of the M-20. It is a 20 ft (6.1 m) sloop rigged scow with a spinnaker. The boat was first built at Melges Boat Works, now Melges Performance Sailboats. The boat has two bilgeboards and two small rudders. After a couple years of experimentation, the class settled on its current rules in 2002.
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
COFC (container on flat car) cars are typically 89 feet (27.13 m) long and carry four 20-foot (6.10 m) intermodal containers or two 40-foot (12.19 m)/45-foot (13.72 m) shipping containers (the two 45-foot or 13.72-metre containers are carryable due to the fact that the car is actually 92 ft or 28.04 m long, over the strike plates).
