Bridges Under Construction
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Viaducts In Buckinghamshire
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Treesitting
Tree sitting is a form of environmentalist civil disobedience in which a protester sits in a tree, usually on a small platform built for the purpose, to protect it from being cut down (speculating that loggers will not endanger human lives by cutting an occupied tree). Supporters usually provide the tree sitters with food and other supplies. About Tree sitting is a strategy that provides a high level of public attention since it is considered to be very dangerous and requires highly-skilled police officers to evict the sitters. Tree sitting is often used as a stalling tactic, to prevent the cutting of trees while lawyers fight in the courts to secure the long-term victories. Tree-sitting was once a children's pastime. In the early 1930s, when endurance contests raged across the U.S., it became a child's contest for kids to climb into their backyard trees and, serviced by siblings and local businesses, attempt to win prizes for the longest sit.

Extinction Rebellion
Extinction Rebellion (abbreviated as XR) is a global environmental movement, with the stated aim of using nonviolent civil disobedience to compel government action to avoid tipping points in the climate system, biodiversity loss, and the risk of social and ecological collapse. Extinction Rebellion was established in the United Kingdom in May 2018 by Gail Bradbrook, Simon Bramwell, and Roger Hallam, along with eight other co-founders from the campaign group Rising Up! Its first major action was to occupy the London Greenpeace offices on 17 October 2018, which was followed by the public launch at the "Declaration of Rebellion" on 31 October 2018 outside the UK Parliament. Earlier that month, about one hundred academics signed a call to action in their support. In November 2018, five bridges across the River Thames in London were blockaded as a protest. In April 2019, Extinction Rebellion occupied five prominent sites in central London: Piccadilly Circus, Oxford Circus, Marble Ar ...

Shock Absorber
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stop HS2
Stop HS2 is a campaign group which opposes the High Speed 2 (HS2) railway project in England. The group was set up in 2010 under the slogan "No business case. No environmental case. No money to pay for it." The following year it organised a conference and it has since challenged MPs, criticised HS2 plans and organised protests. In 2020, the group commented on the Oakervee report and supports illegal camps impeding construction in the Colne Valley Regional Park, Kenilworth and Wendover. Foundation Stop HS2 was set up in 2010 with the aim of stopping High Speed 2 being built, campaigning on both national and local levels. According to the group, construction of the railway and its associated services will destroy woodland, affect local ecosystems and increase carbon emissions. Its slogan is "No business case. No environmental case. No money to pay for it." Stop HS2 has challenged the predicted speeds and capacities of HS2. The group tracks the evolving history of the HS2 projec ...
