mechano-, mechan-; mechanico-; machin-
(Greek makhana, machana > Latin machina: machine, device, tool; an apparatus for applying mechanical power to do work; mekhanikos > machynen, decide a course of action, contrive, plot contrivance; a machine or the workings of machines)
2. A craftsman skilled in operating machine tools and whose occupation is repairing and maintaining automobiles.
3. A worker who is skilled in making, using, or repairing machines, vehicles, and tools.
2. A reference to, relating to, derived from, or concerned with machinery or tools: "In photolithography, a mechanical process that involves a sheet of stiff paper on which the copy for a given plate has been mounted."
"The mechanical procedure results in a finished copy which usually contains hard lettering, type proofs, and art; especially, positioned and mounted so that a photochemical reproduction can be made on a letterpress, offset, or other printing plate."
2. The ratio of the output force to the input force for a machine which transmits mechanical energy: "Mechanical advantage is the work produced by a machine, divided by the force applied to it".
"Actual machines can provide a mechanical advantage that is greater than unity (number or numeral one, oneness); however, the greater the mechanical advantage, the greater the distance which the input force must move in relation to the output force."
2. A materials-processing method for assembling metal constituents with a controlled microstructure by repeated welding, fracturing, and rewelding of a mixture of powder particles, generally in a high-energy ball mill (a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods).
2. A remedy to counteract the effects of a poison or toxin: "The ambulance driver administered the mechanical antidote to the snake bite victim to retard the effects of the toxin during the trip to the hospital."
"The mechanical antidote is administered by mouth, intravenously, or sometimes on the skin, and it may work by directly neutralizing the poison."
2. The areas in a building that include equipment rooms, shafts, stacks, tunnels, and closets used for heating, ventilating, air conditioning, piping, communication, hoisting, conveying, and electrical services.
2. A balance in which the sample weight is determined by comparison with a calibrated weight.
The mechanical balance consists, essentially, of a rigid beam that oscillates on a horizontal central knife-edge as a fulcrum and has the two end knife-edges parallel and equidistant from the center. The loads to be weighed are supported on pans hung from bearings.
2. A radar set in which the radial line inscribed on a transparent disk can be rotated manually around an axis coincident with the center of the plan position indicator.
It is used for determining bearing or location.
2. A change in the double refraction of a solid material when it is subjected to stress.
Infants and young children may have intestinal obstruction present with pain, irritability, vomiting, and abdominal distension.
Small-bowel obstructions progress to decreased or even no bowel movements. Undiagnosed or improperly managed, obstructions can lead to vascular compromise, causing bowel ischemia, necrosis, perforation, and death.
2. The measure of the effectiveness with which a system performs.
It is stated as the ratio of a system's work output to its work input.
In a theoretically frictionless, or ideal, machine, the work input and the work output are equal, and the efficiency would be 1, or 100%.
