A pillow block bearing (or plummer block) is a mounting used to support a rotating shaft with the use of bearings and various accessories. The assembly consists of a mounting block which houses a bearing. [1] The block is mounted to a foundation, and a shaft is inserted, allowing the inner part of the bearing/shaft to rotate. [1] The inside of ...
A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member .
The original pillar would have been 5.24m high, 91 cm wide at the base and 74 cm wide at the top. [3] It is likely to have been formed in four tiers and although the order from top to bottom is reasonably certain from the relative sizes of the blocks, we do not know the rotational order in which the blocks were arranged; there are 64 possibilities.
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
ACI Code 7.10.4.2: For cast-in-place construction, size of spirals shall not be less than 3/8 in. diameter. ACI Code 7.10.4.3: Clear spacing between spirals shall not exceed 3 in., nor be less than 1in. Section 10.9.3 adds an additional lower limit to the amount of spiral reinforcement via the volumetric spiral reinforcement ratio ρ s.
Room and pillar mines are developed on a grid basis except where geological features such as faults require the regular pattern to be modified. The size of the pillars is determined by calculation. The load-bearing capacity of the material above and below the material being mined and the capacity of the mined material determines the pillar size ...
Although bearings tend to wear out with use, designers can make tradeoffs of bearing size and cost versus lifetime. A bearing can last indefinitely—longer than the rest of the machine—if it is kept cool, clean, lubricated, is run within the rated load, and if the bearing materials are sufficiently free of microscopic defects.
Size had a bearing on the fragmentation of the pillars found in the 8th century. The central pillar of Gojuu-no-tou at Hōryūji has a height of 31.5 m with a diameter of 77.8 cm at base, 65.1 cm in the middle and approximately 24.1 cm at the midpoint on the spire.
