Hammering Man, that iconic working stiff in front of the Seattle Arm Museum, is on a break through the end of the year. How many times per minute does he swing that hammer, when he's actually swinging that hammer?
"Lucerne hammer The Lucerne hammer is a type of polearm which was popular in Switzerland during the 15th to 17th centuries. It was a combination of the bec de corbin with the blunt war hammer. The name comes from a discovery of many of these weapons in Lucerne, Switzerland. The 'hammer' was actually a three- to four-pronged head mounted atop a 2m-long (7 foot) polearm stick. It bore a long spike on its reverse, and an even longer spike extending from the very top. It proved effective at puncturing or smashing armor, and much like a man catcher was used"

"A worker, using repeated, relatively soft glancing blows, smooths the metal toward the curvature of the stake. If the metal begins to look dimpled, the worker is using too much force in individual hammer blows. Since planishing hammers are generally in contact with the outside surface of the piece, they are flat, have rounded edges and are polished to avoid marring the work. Pneumatic (air powered) planishing hammers strike hundreds of blows per minute. Care must be taken not to allow sheet metal to work harden and become brittle during planishing. If it does, it must be annealed. Planishing Planishing"

He was most famous for attaching a 700-pound ball and chain around the foot of Jonathan Borofsky's ""Hammering Man"" outside of the Seattle Art Museum and for various other illegal art sculptures left at Westlake Park. These actions ended in July 1996 when Sprinkle's final sculpture caused a bomb scare"
"Hammering Man Hammering Man is a series of monumental kinetic sculptures designed by Jonathan Borofsky which have been installed in various cities around the world. This project was structurally engineered by Leslie E. Robertson Associates (LERA). The first one was a 3.4 m high sculpture at Paula Cooper Gallery made out of wood. Some installations in various museums followed. Outside U.S. installations followed 1985 in Dallas, 1988 in La Jolla and L.A., European installations in Basel 1989, Frankfurt 1990, and others. The most prominent ""Hammering Man"" is 21 metres tall and was commissioned in 1990, for the new Messeturm (exhibition"

Under current leadership, the Hammer's budget has grown from 5 million dollars to roughly 20 million dollars annually, with a full-time staff of over 100. In 1994, Henry Hopkins, then director of the Wight gallery and professor in the Department of Art at UCLA, became director of the Museum. He served in that position until his retirement in 1998. In 1999 Ann Philbin, previously director of The Drawing Center in New York, was named director and still serves as director today. The Hammer Museum"
"during the hammer stroke and increases the energy delivered with each blow. If hammering upwards, gravity reduces the acceleration during the hammer stroke and therefore reduces the energy delivered with each blow. Some hammering methods, such as traditional mechanical pile drivers, rely entirely on gravity for acceleration on the down stroke. A hammer may cause significant injury if it strikes the body. Both manual and powered hammers can cause peripheral neuropathy or a variety of other ailments when used improperly. Awkward handles can cause repetitive stress injury (RSI) to hand and arm joints, and uncontrolled shock waves from repeated impacts"

On December 5, 1991, SAM reopened in a $62 million downtown facility designed by Robert Venturi. The next year, one of Jonathan Borofsky's ""Hammering Man"" sculptures was installed outside the museum as part of Seattle City Light's One Percent for Art program. ""Hammering Man"" would have been installed in time for the museum's opening, but on September 28, 1991, as workers attempted to erect the piece, it fell, was damaged, and had to be returned to the foundry for repairs.

"times the force ""f"" produced by the muscles of the arm and by gravity. When the hammer strikes, the head is stopped by an opposite force coming from the target, equal and opposite to the force applied by the head to the target. If the target is a hard and heavy object, or if it is resting on some sort of anvil, the head can travel only a very short distance ""d"" before stopping. Since the stopping force ""F"" times that distance must be equal to the head's kinetic energy, it follows that ""F"" is much greater than the original"

"Hammer Museum The Hammer Museum, which is affiliated with the University of California, Los Angeles, is an art museum and cultural center known for its artist-centric and progressive array of exhibitions and public programs. Founded in 1990 by the entrepreneur-industrialist Armand Hammer to house his personal art collection, the museum has since expanded its scope to become ""the hippest and most culturally relevant institution in town."" Particularly important among the museum's critically acclaimed exhibitions are presentations of both historically over-looked and emerging contemporary artists. The Hammer Museum also hosts over 300 programs throughout the year, from lectures, symposia, and readings"

"air/steam hammer can deliver up to 300 blows per minute. The possibility of a steam hammer was noted by James Watt (1736–1819) in his 28 April 1784 patent for an improved steam engine. Watt described ""Heavy Hammers or Stampers, for forging or stamping iron, copper, or other metals, or other matters without the intervention of rotative motions or wheels, by fixing the Hammer or Stamper to be so worked, either directly to the piston or piston rod of the engine."" Watt's design had the cylinder at one end of a wooden beam and the hammer at the other. The hammer"
"action). The hammer action is provided by two cam plates that make the chuck rapidly pulse forward and backward as the drill spins on its axis. This pulsing (hammering) action is measured in Blows Per Minute (BPM) with 10,000 or more BPMs being common. Because the combined mass of the chuck and bit is comparable to that of the body of the drill, the energy transfer is inefficient and can sometimes make it difficult for larger bits to penetrate harder materials such as poured concrete. A standard hammer drill accepts 6 mm (1/4 inch) and 13 mm (1/2 inch) drill"

Sledgehammers usually require two hands and a swinging motion involving the entire torso, in contrast to smaller hammers used for driving in nails. The combination of a long swinging range, and heavy head, increases the force of the resulting impact. Sledgehammers are often used in destruction work, for breaking through drywall or masonry walls. Sledgehammers are seldom used in modern mining operations, particularly hand steel. Sledgehammers are also used when substantial force is necessary to"
"to swing the hammer while the smith concentrated on positioning the workpiece. Drop hammers and trip hammers utilize a mechanism to lift the hammer, which then falls by gravity onto the work. In the mid 19th century, manual and rotary-cam hammers began to be replaced in industry by the steam hammer, which was first described in 1784 by James Watt, a Scottish inventor and Mechanical Engineer who also contributed to the earliest steam engines and condensers, but not built until 1840 by British Inventor James Nasmyth. By the late 19th century, steam hammers had increased greatly in size; in 1891"

"following the desired contour. It may sound simple but many months are required to attain competency. A good stone worker can maintain a rhythm of relatively longer blows (about one per second), swinging the hammer in a wider arc, lifting the chisel between blows to flick out any chips that remain in the way, and repositioning it for the next blow. This way, one can drive the point deeper into the stone and remove more material at a time. Some stoneworkers also spin the subbia in their fingers between hammer blows, thus applying with each blow a different part of"

The sliding block has a hole through it that, when reset, is misaligned with the hole through the hammer. When the body is pressed to the trip point, a taper in the body forces the block sideways until the hole in the block is aligned with the hole through the hammer, and the hammer is released to strike the punch.

"hammering method that is universally applicable, requires only a low tech equipment and still offers high reproducibility and the possibility for quality control. The HiFIT hammer operates with a hardened pin with a ball resting on the workpiece with a diameter D of 3 mm. This pin is hammered with an adjustable intensity at around 180–300 Hz at the weld toe. Local mechanical deformations occur in the form of a treatment track. The weld toe is deformed plastically. The induced compressive residual stress prevents the track cracking and the crack propagation on the surface. The International Institute of Welding Technology"

This directly reflects the ratio of strikes to lifting pins on the main wheel, as each turn of the count wheel has to produce 78 strikes ( 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78). One turn of the count wheel = 9.75 turns of the big wheel. The barrel of the striking train can take the necessary 19.5 windings of rope to produce the 156 strikes necessary to run a full 24 hours."
"still widely used because of its shock-absorbing qualities and repair-ability. Mechanically-powered hammers often look quite different from the hand tools, but nevertheless, most of them work on the same principle. They include: In professional framing carpentry, the manual hammer has almost been completely replaced by the nail gun. In professional upholstery, its chief competitor is the staple gun. A hammer is a simple force amplifier that works by converting mechanical work into kinetic energy and back. In the swing that precedes each blow, the hammer head stores a certain amount of kinetic energy—equal to the length ""D"" of the swing"
"Hammer mill A hammer mill, hammer forge or hammer works was a workshop in the pre-industrial era that was typically used to manufacture semi-finished, wrought iron products or, sometimes, finished agricultural or mining tools, or military weapons. The feature that gave its name to these workshops was the water-driven trip hammer, or set of hammers, used in the process. The shaft, or 'helve', of the hammer was pivoted in the middle and the hammer head was lifted by the action of cams set on a rotating camshaft that periodically depressed the end of the shaft. As it rose and fell,"

Instead, the handles must be rhythmically moved back and forth at an appropriate frequency, depending on the physical phenomenon of mechanical resonance to build up enough energy to strike the chimes.
