handloading or reloading is the process of making firearm cartridges or shells by manually assembling the individual components case, primer, propellant, and projectile such as bullet, slug or shots , rather than purchasing mass-assembled, factory-loaded ammunition.. the term handloading is the more generic term, as it refers to manual assembly of ammunition using components from any source.
a pile driver is a device used to drive piles into soil to provide foundation support for buildings or other structures. the term is also used in reference to members of the construction crew that work with pile-driving rigs. one type of pile driver uses a weight placed between guides so that it can slide vertically.
vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point.the word comes from latin vibrationem 'shaking, brandishing' . the oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.. vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or .
john ernst worrell keely september 3, 1837 – november 18, 1898 was a fraudulent american inventor from philadelphia who claimed to have discovered a new motive power which was originally described as 'vaporic' or 'etheric' force, and later as an unnamed force based on 'vibratory sympathy', by which he produced 'interatomic ether' from water and air.

the hayward fault zone is a geologic fault zone capable of generating destructive earthquakes.this fault is about 74 mi 119 km long, situated mainly along the western base of the hills on the east side of san francisco bay.it runs through densely populated areas, including richmond, el cerrito, berkeley, oakland, san leandro, castro valley, hayward, union city, fremont, and san jose.
the queen bee's abdomen is longer than the worker bees surrounding her and also longer than a male bee's. even so, in a hive of 60,000 to 80,000 honey bees, it is often difficult for beekeepers to find the queen with any speed; for this reason, many queens in non-feral colonies are marked with a light daub of paint on their thorax.
vibratory feeders, commonly known as a bowl feeder, are self-contained devices, consisting of a specially shaped bowl designed to orient the parts to a specific orientation. a vibrating drive unit, upon which the bowl is mounted and a variable-amplitude control box controls the bowl feeder.
microelectromechanical systems mems , also written as micro-electro-mechanical systems or microelectronic and microelectromechanical systems and the related micromechatronics and microsystems constitute the technology of microscopic devices, particularly those with moving parts. they merge at the nanoscale into nanoelectromechanical systems nems and nanotechnology.
an electric motor is an electrical machine that converts electrical energy into mechanical energy. most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
a crisis in the dc universe is an event with potentially great consequences, often involving multiple universes and sometimes even threatening their existence.. from 1963 to 1985 the term 'crisis' was used to describe the annual events in which the justice league of america of earth-one and the justice society of america of earth-two met and worked together, usually in an incident involving .
i have removed the following section as michael faraday demonstrated the electric motor in 1821 and discovered the dynamo effect in 1831. maybe somebody could check the maxwell quote. == some history and interconnection == 'the construction of an electric motor is very similar to that of a dynamo.in fact, a machine can be built that acts as either a motor or a dynamo.
the wolseley hornet is a six-cylinder twelve fiscal horsepower lightweight automobile which was offered as a saloon car, coupé and open two-seater as well as the usual rolling chassis for bespoke coachwork. produced by wolseley motors limited from 1930 to 1936, the hornet was unveiled to the public at the end of april 1930. wolseley had been bought from the receivers by william morris in 1927.
carpenter's hammer used for nailing , such as the framing hammer and the claw hammer, and pinhammers ball-peen and cross-peen types cow hammer – sometimes used for livestock slaughter, a practice now deprecated due to animal welfare objections; cross-peen hammer, having one round face and one wedge-peen face.
a damped sine wave is a sinusoidal function whose amplitude approaches zero as time increases.. damped sine waves are commonly seen in science and engineering, wherever a harmonic oscillator is losing energy faster than it is being supplied.
