5. You are just a wheeled, self-powered motor vehicle used
for transportation. Most definitions of the term specify that cars are
designed to run primarily on roads, to have seating for one to eight
people, to typically have four wheels, and to be constructed principally for
the transport of people rather than goods.-
Carth vader
21. An airplane or aero plane (informally plane) is a powered, fixed-wing
aircraft that is propelled forward by thrust from a jet engine or
propeller. Airplanes come in a variety of sizes, shapes,
and wing configurations. The broad spectrum of uses for airplanes
includes recreation, transportation of goods and people, military, and
research. Most airplanes are flown by a pilot on board the aircraft, but
some are designed to be remotely or computer-controlled.

tested in 1939.

39. Mechanized
agriculture is the
process of
using agricultural
machinery to mechaniz
e the work
of agriculture, greatly
increasing farm
worker productivity. In
modern times, powered
machinery has replaced
many jobs formerly
carried out by men or
animals such as oxen ,
horses and mules.
40. A mechanical seed spacing and depth placing
device that increased crop yields and saved seed
41. Steam power was
applied to threshing
machines in the late
19th century. There
were steam engines
that moved around on
wheels under their
own power for
supplying temporary
power to stationary
threshing machines.
These were
called road engines.
47. Air conditioning (often referred to
as A/C, AC or aircon) is the process of altering the
properties of air (primarily temperature
and humidity) to more comfortable conditions,
typically with the aim of distributing the conditioned
air to an occupied space to improve thermal
comfort and indoor air quality.
48. The 2nd-century Chinese
inventor Ding Huan of
the Han Dynasty invented
a rotary fan for air
conditioning, with seven
wheels 3 m (9.8 ft) in
diameter and manually
powered.
49. In 1902, the first
modern electrical
air conditioning
unit
was invented by
Willis
Carrier in Buffalo,
New York
59. Refrigeration is a
process in which work
is done to
move heat from one
location to another.
The work of heat
transport is
traditionally driven
by mechanical work,
but can also be driven
by
heat, magnetism, ele
ctricity, laser, or other
means.
60. ICE HARVESTING
Before 1830, few Americans used ice to
refrigerate foods due to a lack of ice-storehouses
and iceboxes. As these two things
became more widely available, individuals used
axes and saws to harvest ice for their
storehouses. This method proved to be difficult,
dangerous, and certainly did not resemble
anything that could be duplicated on a
commercial scale.

68. Materials science, also commonly
known as materials science and engineering,
is an interdisciplinary field which deals with
the discovery and design of new materials.
Though it is a relatively new scientific field
that involves studying materials through the
materials paradigm (synthesis, structure,
properties and performance), its intellectual
origins reach back to the emerging fields of
chemistry, mineralogy and engineering
during the Enlightenment.
73. Graphene. It is a one-carbon
atom thick. It is
like a paper sheet of
carbon. Because of its
unique composition and
structure it also has
some unique
characteristics and
because it is unique it
means some of these
characteristics only
belong to graphene. It
has many traits that are
individually if not
partially utilized in
different areas of
engineering
