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.-

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.

39. Mechanized
agriculture is the process
of using agricultural
machinery to mechanize t
he 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

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, elec
tricity, laser, or other
means. Refrigeration

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
