Under the Whyte notation for the classification of steam locomotives, a 2-8-8-8-8-2 has two leading wheels, four sets of eight driving wheels, and two trailing wheels. Because of its length, such a locomotive must be an multiplex locomotive. It is longer than a normal articulated locomotive; the fourth set of drivers is located under the tender.
In the past, car tires used inner tubes, but most cars now use tubeless tires that hold air without an inner tube. Tubeless tires offer advantages, as they can operate at both low and high pressures without the risk of pinching or bursting, unlike tube tires. [2] Large inner tubes are used for various recreational activities, such as flotation ...
[1] The Glagolitic alphabet was an early Slavic alphabet, the predecessor of the modern Cyrillic alphabet. In Croatia, the Catholic Church gave permission for the Roman Rite liturgical Mass to be celebrated in Old Church Slavonic at a time when such liturgies were typically only permitted to be in Latin, resulting in the Glagolitic Use Mass.

The 2-8-2 wheel arrangement has a single pair of leading wheels in a leading truck, followed by four coupled pairs of driving wheels and a pair of trailing wheels in a trailing truck. Since the 2-8-2 type was known as Mikado , the corresponding Garratt and Modified Fairlie types were usually known as Double Mikado .
The earliest wheelbarrows with archaeological evidence in the form of a one-wheel cart come from second-century Han dynasty Emperor Hui's tomb murals and brick tomb reliefs. [1] The painted tomb mural of a man pushing a wheelbarrow was found in a tomb at Chengdu, Sichuan province, dated precisely to 118 AD. [2]
The 2-2-2-0 wheel arrangement was first used on some locomotives introduced on the Eastern Counties Railway by John Chester Craven between 1845 and 1847, and some Crampton locomotives on the South Eastern Railway in 1849. [4] However the 2-2-2-0 type is usually associated with Francis Webb of the London and North Western Railway who between ...
In the tire factory, the tire and wheel are mounted on a balancing machine test wheel, the assembly is rotated at 100 r/min (about 5–7 m/s (18–25 km/h; 11–16 mph) with recent high sensitivity sensors) or higher, 300 r/min (about 25–27 m/s (90–97 km/h; 56–60 mph) with typical low sensitivity sensors), and forces of unbalance are ...
The external threads at the tip of both "threaded" and "unthreaded" Presta valves are 5V2 (#12-24TPI), which measures out to 5.2×1.058 mm, [8] the same thread size as the tip of a Dunlop valve. The external threads on the main body of "threaded" Presta valves are 6V1, which measures 6×0.80 mm. [ 8 ]
