Functioning
The premise of the lemon squeezer is simple: Pressure is exerted on a lemon to force its juice and pulp from its rind; the juice and pulp often escape through a filter or sieve. The squeezer itself must resist the pressure, so soft, easily deformable materials cannot be used. Because the lemon juice is very acidic, the squeezer can only be made of acid-resistant materials.
Among squeezers that employ a twisting central projection, both manual and electric options exist; for the manual squeezer the operator must turn the device and hold the lemon (or turn and hold the lemon) while the electric squeezer turns it automatically and the operator must simply hold onto the lemon. Other squeezers simply crush the lemon against a stationary central projection; these usually employ long handles, to gain the mechanical advantage of a lever.

Famous quotes containing the word functioning:
“Wisdom is not just knowing fundamental truths, if these are unconnected with the guidance of life or with a perspective on its meaning. If the deep truths physicists describe about the origin and functioning of the universe have little practical import and do not change our picture of the meaning of the universe and our place within it, then knowing them would not count as wisdom.”
—Robert Nozick (b. 1938)
“Anyone who wishes to combine domestic responsibilities and paid employment with the least stress and most enjoyment might start by pondering this paradox: the first step to better functioning is to stop blaming herself for not functioning well enough.”
—Faye J. Crosby (20th century)
“Ideals possess the strange quality that if they were completely realized they would turn into nonsense. One could easily follow a commandment such as “Thou shalt not kill” to the point of dying of starvation; and I might establish the formula that for the proper functioning of the mesh of our ideals, as in the case of a strainer, the holes are just as important as the mesh.”
—Robert Musil (1880–1942)
