The following is a list of features you may consider:
• An ice-maker produces a continuous supply of ice and a frostless refrigerator (also referred to as frost-
free) refers to models that automatically prevent ice build-up through a process of constant evaporation.
• A water filtration system provides a ready supply of ice water and ice cubes without opening the
freezer door.
• Spill-proof glass shelves are easier to clean than wire shelves and the built-in lip of these glass shelves
also helps contain spills.
• A temperature control meat drawer with its own temperature controls and cold air supply allows you to
keep meat longer.
• Flexible space allows you to adjust door shelf bins and interior shelves to fit your size needs.
• A crisper drawer has a special built-in humidity control that extends the life of fruits and vegetables.
• A wine/beverage rack refrigerates cans and bottles on their side to conserve space and gallon door bins
are the perfect place for bulky items such as milk and oversized soft drink bottles.
• An egg/deli door bin stores eggs or can be converted to drawer storage.

A FEW WORDS ABOUT GENERAL
ENGINEERING SUBJECTS
Mathematics is the science of space and quantity, concerned with concrete bodies and collections; it is now
recognized to be a vast aggregation of deductions from assumptions about pure abstractions.
Mathematics comprises several large branches. The first of these is arithmetic.
Arithmetic is concerned with numbers and numerical calculations. Algebra goes beyond arithmetic by
greatly extending the symbolism. In particular, algebra utilizes letters for unknown, or specified, numbers. This
makes it possible to deal with known and unknown numbers on an equal footing. A large body of algebra is the
theory of equations.
Geometry is a vast field of mathematics with many subdivisions. The basic elements of geometry are
points, lines, and planes. More complicated elements, such as triangles, circles, and cubes, are defined in terms
of the undefined elements.
Descriptive geometry is as much a branch of mechanical drawing as of mathematics. It is concerned largely
with representing three dimensions on a flat surface so that each part is accurately represented.
Whether mathematical physics belongs to physics or mathematics is determined by one's viewpoint. It is
mathematics applied to physical problems. Quantum theory and the theory of relativity are examples.
Physics is the systematic study of natural phenomena to dibasic laws governing them. Traditionally physics
is divided into several major topics, namely, mechanics, heat, optics, electricity and magnetism, atomic physics
and nuclear physics. Because of the remarkable unity of Nature this separation into topics is, to some extent,
artificial and only exists for convenience. Newton's second law, relating force to acceleration, ration, and his
third law, relating action and reaction, form the basis of mechanics. Maxwell's equations, which combine in
mathematical the laws discovered by Ampere, Coulomb and Faraday, form the basis of electricity and magnet-
ism and optics.
Mechanics is the oldest branch of physics, dealing with the state of rest or motion of particles and rigid
bodies and with forces acting on bodies. The subject has three main branches: statics, dynamics and fluid me-
chanics. In statics, the forces acting on the body, or system of bodies, are so arranged that the body is in equi-
librium.
Dynamics deals with systems in motion and may be divided into kinetics, the study of the effect of forces in
changing the motion of bodies, and kinematics in which the motion of particles or rigid bodies is considered
without reference to the forces producing the motion.
Fluid mechanics includes the theory of gases, hydrodynamics (the motion of liquids), and aerodynamics.
The mathematical development of results and theories arising from classical mechanics is called analytical me-
chanics.
