1.1 Telescopic crane: The present work is carried out on telescopic crane. A telescopic hydraulic crane has a boom that consists of a number of tubes fitted one inside the other. A hydraulic or other powered mechanism extends or retracts the tubes to increase or decrease the total length of the boom. It uses one or more simple machines to create mechanical advantage and thus moves loads beyond the normal capability of human. These types of booms are often used for short term construction projects

Science in the Seventeenth Century In this paper, I will discuss the different viewpoints taken by scientists and philosophers such as Rene Descartes, Hero of Alexandria, Nicholas Steno, and Isaac Newton during the seventeenth century regarding their explanations of nature or the use of the forces of nature. Descartes and Hero of Alexandria studied and wrote papers prior to 1640; Steno and Newton wrote papers after 1640. Rene Descartes, the “Father of Modern Philosophy” and a scientist, believed

door, it could easily weigh over 200 pounds. The fact that your garage door usually feels like it weighs almost nothing at all is by design. Simply dealing with this much weight can be dangerous. In the second place, the springs that act as a counterweight in your garage door can store a lot of potential kinetic energy. If you lose your grip or if they otherwise snap when you're trying to install them, they can cause severe injuries to you or anyone nearby. Letting your residential garage door repair

The Scottish Rite Cathedral has a capacity of 1,600 with a fully equipped stage, four manual organs of 70 stops, a counterweight system of 100 sets of lines and a remote control five color switchboard making it ideal for a variety of productions, shows, and events. There are 28 units in this building that can be divided into three different divisions. These are the ritualistic tower, the auditorium, and the shrine club.

Since Egypt was a desert, water was very important. They dug canals (long ditches) to help them bring water into their fields. They also built shadufs to help with irrigation. A shaduf is a basic tool that used a bucket and a counterweight on a long stick to help lift water out of the Nile River. Egyptians also tamed animals to help them with their farm jobs. Animals trampled seeds and pulled ploughs. Other tools they made and used were rakes, hoes, flint-bladed sickles and winnowing

The first records of counterweight trebuchets began appearing in the 12th century. Proving to be an excellent siege weapon, many militaries began using this. Though stone-throwing artillery had been employed by both the Greeks and Romans, they were usually powered by torsion or tension; the trebuchet was the first war machine to use gravity and leverage to fire projectiles.They were used widely during the Crusades, in which the European militaries, especially the French, used the trebuchet to lay

Unions are important in today’s society because checks and balances are necessary entities in business and government, so if CEOs are just focusing on themselves

weighing over a thousand pounds, it “featured a groundbreaking clutch system that could reverse direction without having to turn the oxen around.” He later made other lifting machines, including the “castello, a 65-foot-tall crane with a series of counterweights and hand screws to move loads laterally once they’d been raised to the right height.” The significance of these discoveries was that Brunelleschi invented machinery that can help others lift heavy objects for their own domes. They also modified
