Travel To See Big Ben Clock London
Big Ben, the tower clock, is known for its accuracy and massive bell. Specifically, the name refers to the great bell, which weighs 15.1 tons (13.7 metric tons) but is generally associated with the entire clock tower at the north end of the Houses of Parliament in Westminster, London. The tower was formally named the St. Stephen's Tower in 2012 in honor of Elizabeth II's Diamond Jubilee, which celebrates 60 years on the British throne.
The clock hands are 2.7 m (9 ft) and 4.3 (14 ft), respectively, and the clock tower rises to 97.5 m (320 ft). Coordinated initially with the Royal Greenwich Observatory, Big Ben's Chimes has been broadcast as a daily radio signal for the British Broadcasting Corporation (BBC) since 1924.
The watch was designed by Edmund Beckett Dennison (later Sir Edmund Beckett and Lord Grimthorpe), Sir George Erie (then Royal Astronomer), and watchmaker Edward Dent.
Dennison's main contribution was a new gravitational escape that gave the clock unprecedented accuracy. A jumping wheel is allowed in a pendulum watch to rotate across one tooth pitch, leading to every double swing of the Pendulum. A perfect escape transmits impulse without interrupting free movement, and the desire must be as uniform as possible. This is the second realization of the two-legged gravitational escape that Denison created for Big Ben. Big Ben gets hurt three times a week, and the wind takes about an hour.
Big Ben is accurate within two seconds per week. The Pendulum is made by adding a penny made in 1971 to the UK currency. Every penny, Big Ben gets 0.4 seconds per day.
Dent won the large watchmaking commission in 1852 but died before the project was completed, which was later completed by his son Frederick Dent. In 1859 the clock and the bell were installed together. Some historians call the nickname for Sir Benjamin Hall, the Commissioner of Works.
The first bell casting failed; The second casting was done by George Myers of the White chapel Bell Foundry and towed by a team of 16 horses. Shortly after its installation, it also suffered a crack and was laid off in service until it was repaired in 1862. Big Ben's bell remained silent for two years during World War I to prevent hostile aircraft from being used in the Houses of Parliament, and during World War II, its watch was not lit. The bell was restored and repaired in 1934 and 1956. Maintenance was done in 2007 on the clock. On August 21, 2017, Big Ben stopped chiming. While the tower was undergoing a four-year renovation project, the bell rang for special events, especially on New Year's Eve and Memorial Sunday.
