Hit it hard with a hammer. Either the lock will break open, usually what happens, or you'll break whatever the lock is on.
Joshua Andrews invented the make and break engine in 1726. he invented it to power a snowmobiel called a Yamaha bravo. its a 5.3L v8 256hp engine.
The thinner section of the dogbone will break before the thicker parts at the end. Both ends are held by grippers so the last place you want the specimen to break is at the ends.
The Concorde was a supersonic commercial airliner. However, due to flight accidents the Concorde is no longer in service. The typical cruise speed for a commercial jet is about 0.8 Mach. Of course, almost any plane with sufficient engines and built for speed can dive down and break the sound barrier---but it may not recover from this.
The steel has a ductile material properties so that it could be elongate at a point of ultimate yield point.It is stable while before the break point
In 1852
in 1850!
it was easy!
He invented a elevator with a safty break.
elisha was American and was the actual inventor of the elevator break in 1850
Yonkers, New York Incorrect question being asked, Elisha did not invent the elevator, he invented the safety break system. As welll as invented an automatic bread baking oven.
Elisha Otis is known for building the first modern passenger elevator which used his invention of a safety device which prevented the car from falling if the cables broke. The elevator safety brake was first demonstrated at the Crystal Palace Exposition in New York in 1854. After ascending in his new elevator, Otis called for the elevator's cable to be cut with an axe. Instead of falling, the elevator platform held, secured by a brake using toothed guiderails in the elevator shaft and a spring-loaded bar that automatically caught in the toothed rail of the elevator car if the cable failed. Today, the Otis Elevator Company is the world's largest company in the manufacture and service of elevators, escalators, moving walks and people-moving equipment.
In 1852, Elisha Otis invented a freight elevator equipped with a safety device to prevent falling in case the supporting cable would break.
An elevator by definition is a platform or an enclosure raised and lowered in a vertical shaft to transport people and freight. The shaft contains the operating equipment, motor, cables, and accessories.Primitive elevators were in use as early as the 3rd century BC, operated by human, animal, or water wheel power. In 1743, a counter-weighted, man-powered, personal elevator was built for King Luis XV connecting his apartment in Versailles with that of his mistress, Madame de Chateauroux, whose quarters were one floor above King Luis.19th Century ElevatorsFrom about the middle of the 19th century, elevators were powered, often steam-operated, and were used for conveying materials in factories, mines, and warehouses. In 1823, two architects Burton and Hormer built an "ascending room" as they called it, this crude elevator was used to lift paying tourists to a platform for a panorama view of London. In 1835, architects Frost and Stutt built the "Teagle", a belt-driven, counter-weighted, and steam-driven lift was developed in England.Hydraulic CraneIn 1846, Sir William Armstrong introduced the hydraulic crane, and in the early 1870s, hydraulic machines began to replace the steam-powered elevator. The hydraulic elevator is supported by a heavy piston, moving in a cylinder, and operated by the water (or oil) pressure produced by pumps. Elisha OtisIn 1853, American inventor Elisha Otis demonstrated a freight elevator equipped with a safety device to prevent falling in case a supporting cable should break. This increased public confidence in such devices. In 1853, Elisha Otis established a company for manufacturing elevators and patented (1861) a steam elevator. While, Elisha Graves Otis did not actually invent the first elevator, he did invent the brake used in modern elevators, and his brakes made skyscrapers a practical reality. In 1857, Elisha Otis and the Otis Elevator Company began manufacturing passenger elevators. A steam-powered passenger elevator was installed by the Otis Brothers in a five-story department store owned by E.W Haughtwhat & Company of Manhattan. It was the first public elevator.
it was invented in 1906
Elevator cables can break, but the elevator car has several safety mechanisms:the elevator is maintained regularly and checked whether fit for usethere are redundant cables so that if some break the others can still bear the loadthe brakes on the car are designed to come on if there OS a power failurethe car is designed to latch onto the rail if it falls too quickly
