00:00:01.860 --> 00:00:04.860
laughs

3
00:00:04.920 --> 00:00:09.179
assembly line for kids hey kids have you

4
00:00:09.179 --> 00:00:10.860
ever thought about how things are made

5
00:00:10.860 --> 00:00:14.219
all of the objects machines and

6
00:00:14.219 --> 00:00:16.500
electronic Goods all around you well

7
00:00:16.500 --> 00:00:18.900
think about it everything you see that

8
00:00:18.900 --> 00:00:20.939
isn't natural had to have been made by

9
00:00:20.939 --> 00:00:23.039
someone your bike

10
00:00:23.039 --> 00:00:25.980
your mom and dad's car the computer or

11
00:00:25.980 --> 00:00:27.900
smartphone you and your family might use

12
00:00:27.900 --> 00:00:31.520
it all had to be made by someone somehow

13
00:00:31.520 --> 00:00:34.680
originally even the simplest stuff was

14
00:00:34.680 --> 00:00:37.440
made by humans using only their hands

15
00:00:37.440 --> 00:00:40.320
and maybe some basic tools imagine

16
00:00:40.320 --> 00:00:43.739
living a long long time ago when

17
00:00:43.739 --> 00:00:45.780
everything had to be made from scratch

18
00:00:45.780 --> 00:00:49.260
by hand the first will was literally

19
00:00:49.260 --> 00:00:52.320
chiseled out of stone or wood to make it

20
00:00:52.320 --> 00:00:55.440
round so it could roll houses were Huts

21
00:00:55.440 --> 00:00:57.840
that were either carved or built by hand

22
00:00:57.840 --> 00:01:02.760
out of wood mud rocks straw hay and

23
00:01:02.760 --> 00:01:06.299
other materials early on wood from trees

24
00:01:06.299 --> 00:01:09.900
was used to make beds desks or tables

25
00:01:09.900 --> 00:01:12.479
can you imagine trying to build a piece

26
00:01:12.479 --> 00:01:14.520
of furniture like that without at least

27
00:01:14.520 --> 00:01:17.580
a few simple tools as time went on

28
00:01:17.580 --> 00:01:20.520
people figured out how to make and use

29
00:01:20.520 --> 00:01:23.340
better and more efficient tools that

30
00:01:23.340 --> 00:01:25.259
would allow them to build stuff more

31
00:01:25.259 --> 00:01:27.420
easily hammers

32
00:01:27.420 --> 00:01:32.880
saws chisels pulleys hand carts and

33
00:01:32.880 --> 00:01:35.520
other devices were created so that more

34
00:01:35.520 --> 00:01:37.500
and more complicated things could be

35
00:01:37.500 --> 00:01:40.740
created with less effort during colonial

36
00:01:40.740 --> 00:01:43.078
times certain people had very

37
00:01:43.078 --> 00:01:46.020
specialized skills and their jobs were

38
00:01:46.020 --> 00:01:48.079
to make the things the community needed

39
00:01:48.079 --> 00:01:51.299
clothing was sewn by hand

40
00:01:51.299 --> 00:01:54.180
a cobbler made shoes

41
00:01:54.180 --> 00:01:57.360
Farmers planted and harvested crops

42
00:01:57.360 --> 00:02:01.100
Coopers made wooden tubs or kegs

43
00:02:01.100 --> 00:02:04.320
blacksmiths worked with iron

44
00:02:04.320 --> 00:02:06.840
a Tanner converted animal skins into

45
00:02:06.840 --> 00:02:10.139
leather and basket Weavers made well

46
00:02:10.139 --> 00:02:14.400
baskets this work was arduous and took a

47
00:02:14.400 --> 00:02:17.639
lot of time at some point people started

48
00:02:17.639 --> 00:02:20.120
saying there's got to be an easier way

49
00:02:20.120 --> 00:02:22.560
and there was

50
00:02:22.560 --> 00:02:25.440
during the Industrial Revolution things

51
00:02:25.440 --> 00:02:28.680
changed people came up with the idea of

52
00:02:28.680 --> 00:02:31.379
interchangeable parts meaning that parts

53
00:02:31.379 --> 00:02:33.540
from one thing could be used in

54
00:02:33.540 --> 00:02:34.739
something else

55
00:02:34.739 --> 00:02:37.200
all of a sudden machines didn't require

56
00:02:37.200 --> 00:02:40.139
unique Parts they could be changed from

57
00:02:40.139 --> 00:02:41.700
one to another

58
00:02:41.700 --> 00:02:45.599
take your bike for example the seat

59
00:02:45.599 --> 00:02:47.819
the wheels

60
00:02:47.819 --> 00:02:51.480
the nuts and bolts all of the things on

61
00:02:51.480 --> 00:02:54.360
your bicycle can be used on other bikes

62
00:02:54.360 --> 00:02:57.060
and nuts and bolts from something like a

63
00:02:57.060 --> 00:02:59.160
bike can be used on different types of

64
00:02:59.160 --> 00:03:01.919
machines this is the idea behind

65
00:03:01.919 --> 00:03:05.099
interchangeable parts a caveman might

66
00:03:05.099 --> 00:03:07.980
say why didn't I think of that

67
00:03:07.980 --> 00:03:10.800
the use of interchangeable parts was

68
00:03:10.800 --> 00:03:13.739
actually a French idea used initially to

69
00:03:13.739 --> 00:03:18.180
make guns but in 1798 it came to America

70
00:03:18.180 --> 00:03:20.879
our founding father and first President

71
00:03:20.879 --> 00:03:24.480
George Washington loved the idea so much

72
00:03:24.480 --> 00:03:27.840
he commissioned Eli Whitney to make guns

73
00:03:27.840 --> 00:03:30.599
here using interchangeable parts

74
00:03:30.599 --> 00:03:33.780
eventually Eli took that idea and

75
00:03:33.780 --> 00:03:36.140
invented his famous cotton gin machine

76
00:03:36.140 --> 00:03:40.040
which revolutionized the cotton industry

77
00:03:40.040 --> 00:03:42.780
interchangeable parts really put product

78
00:03:42.780 --> 00:03:45.720
manufacturing on a roll leading to labor

79
00:03:45.720 --> 00:03:48.659
unions changes in people's salary and

80
00:03:48.659 --> 00:03:50.580
the cost of making things and

81
00:03:50.580 --> 00:03:52.620
adjustments to how much time people were

82
00:03:52.620 --> 00:03:55.319
willing to work each day our consumer

83
00:03:55.319 --> 00:03:58.799
Society was really starting to grow but

84
00:03:58.799 --> 00:04:01.500
nothing changed manufacturing more than

85
00:04:01.500 --> 00:04:04.319
what Ransom olds developed and patented

86
00:04:04.319 --> 00:04:08.700
in 1901 to help him make cars this was

87
00:04:08.700 --> 00:04:12.360
huge it was called the assembly line you

88
00:04:12.360 --> 00:04:15.060
may have heard of it but what exactly is

89
00:04:15.060 --> 00:04:18.299
it well let's say for example that

90
00:04:18.299 --> 00:04:20.100
you're put in charge of decorating the

91
00:04:20.100 --> 00:04:22.979
school dance and you decide to make 100

92
00:04:22.979 --> 00:04:25.979
colorful stars to hang up all over the

93
00:04:25.979 --> 00:04:29.040
cafeteria you could start by drawing and

94
00:04:29.040 --> 00:04:31.740
cutting one star yourself then coloring

95
00:04:31.740 --> 00:04:34.199
it then sticking it to the wall then

96
00:04:34.199 --> 00:04:37.259
starting on the next one only 99 to go

97
00:04:37.259 --> 00:04:39.779
think about how long that would take for

98
00:04:39.779 --> 00:04:43.560
forever right a faster and easier way

99
00:04:43.560 --> 00:04:46.199
would be to recruit some friends and set

100
00:04:46.199 --> 00:04:48.900
up an assembly line so that while one

101
00:04:48.900 --> 00:04:51.660
person draws one could cut yet another

102
00:04:51.660 --> 00:04:54.000
person could color while a fourth could

103
00:04:54.000 --> 00:04:57.300
hang the Stars up that way more stars

104
00:04:57.300 --> 00:04:59.639
could be made in less time you could be

105
00:04:59.639 --> 00:05:02.220
drawing more and more stars while the

106
00:05:02.220 --> 00:05:04.620
rest of the process is being done by the

107
00:05:04.620 --> 00:05:07.560
other three people the whole point of an

108
00:05:07.560 --> 00:05:09.660
assembly line is that the parts or

109
00:05:09.660 --> 00:05:12.479
processes for a product are completed in

110
00:05:12.479 --> 00:05:15.540
a sequence by individual workers no

111
00:05:15.540 --> 00:05:17.880
single worker is responsible for the

112
00:05:17.880 --> 00:05:20.580
entire finished product each worker or

113
00:05:20.580 --> 00:05:23.520
machine does one part and then the parts

114
00:05:23.520 --> 00:05:25.500
are put together to make the finished

115
00:05:25.500 --> 00:05:28.680
object with this approach the product is

116
00:05:28.680 --> 00:05:30.900
made much more quickly and much more

117
00:05:30.900 --> 00:05:33.600
efficiently not to mention at a lower

118
00:05:33.600 --> 00:05:36.660
cost when olds tried this to make his

119
00:05:36.660 --> 00:05:39.720
cars in 1901 he found that production

120
00:05:39.720 --> 00:05:43.740
increased by 500 percent that's five

121
00:05:43.740 --> 00:05:45.960
times the number of cars that he could

122
00:05:45.960 --> 00:05:48.779
then sell to customers for the first

123
00:05:48.779 --> 00:05:51.600
time someone was able to crank out brand

124
00:05:51.600 --> 00:05:54.020
new automobiles in large numbers

125
00:05:54.020 --> 00:05:56.400
combined with interchangeable parts

126
00:05:56.400 --> 00:05:58.860
skilled workers on the assembly line

127
00:05:58.860 --> 00:06:02.520
became a well-oiled machine making cars

128
00:06:02.520 --> 00:06:04.740
quickly and allowing them to spend less

129
00:06:04.740 --> 00:06:07.440
time toiling at work and more time

130
00:06:07.440 --> 00:06:09.120
hanging out with their families and

131
00:06:09.120 --> 00:06:12.060
friends it's hard to argue with that

132
00:06:12.060 --> 00:06:16.680
between 1908 and 1915 another car maker

133
00:06:16.680 --> 00:06:20.100
Henry Ford seized on this idea and

134
00:06:20.100 --> 00:06:23.460
improved it he started using a conveyor

135
00:06:23.460 --> 00:06:25.259
system like this

136
00:06:25.259 --> 00:06:28.259
check it out in this system the main

137
00:06:28.259 --> 00:06:31.380
part of the car or the chassis got towed

138
00:06:31.380 --> 00:06:33.900
by a rope that moved it from Station to

139
00:06:33.900 --> 00:06:37.259
Station at each station a worker would

140
00:06:37.259 --> 00:06:40.020
then add a part to the vehicle as people

141
00:06:40.020 --> 00:06:42.240
at later stations were putting on Parts

142
00:06:42.240 --> 00:06:44.639
workers at the beginning were already

143
00:06:44.639 --> 00:06:47.400
starting a new one genius

144
00:06:47.400 --> 00:06:50.880
Ford was able to crank out one car every

145
00:06:50.880 --> 00:06:53.880
hour and a half using this method or a

146
00:06:53.880 --> 00:06:57.300
whopping 2 million cars a year back then

147
00:06:57.300 --> 00:06:59.880
that was an incredible number

148
00:06:59.880 --> 00:07:02.639
to this day Ford is known as the father

149
00:07:02.639 --> 00:07:05.520
of the assembly line or the father of

150
00:07:05.520 --> 00:07:08.819
Automotive mass production once Ford's

151
00:07:08.819 --> 00:07:11.300
system was in place things took off

152
00:07:11.300 --> 00:07:13.800
everything started being made by

153
00:07:13.800 --> 00:07:17.479
conveyor assemblies including toys

154
00:07:17.479 --> 00:07:19.440
radios

155
00:07:19.440 --> 00:07:21.680
furniture

156
00:07:21.680 --> 00:07:25.800
planes appliances and other consumer

157
00:07:25.800 --> 00:07:29.099
items American consumerism would never

158
00:07:29.099 --> 00:07:30.539
be the same

159
00:07:30.539 --> 00:07:32.940
these days things have gone a step

160
00:07:32.940 --> 00:07:35.699
further assembly lines are made up of

161
00:07:35.699 --> 00:07:39.000
robots and machines a person is only

162
00:07:39.000 --> 00:07:41.580
necessary to either oversee the whole

163
00:07:41.580 --> 00:07:43.800
thing or make sure the product is put

164
00:07:43.800 --> 00:07:46.740
together correctly at the end the use of

165
00:07:46.740 --> 00:07:49.759
machines has changed everything

166
00:07:49.759 --> 00:07:52.560
manufacturers no longer need as many

167
00:07:52.560 --> 00:07:55.160
skilled workers to put products together

168
00:07:55.160 --> 00:07:57.720
instead they need people who understand

169
00:07:57.720 --> 00:08:00.479
technology to program and troubleshoot

170
00:08:00.479 --> 00:08:03.240
the computers and machines that do all

171
00:08:03.240 --> 00:08:06.180
the heavy lifting these computer experts

172
00:08:06.180 --> 00:08:08.699
have replaced the skilled workers who

173
00:08:08.699 --> 00:08:11.580
used to work on the assembly line these

174
00:08:11.580 --> 00:08:13.919
types of assembly lines have also made

175
00:08:13.919 --> 00:08:16.740
the cost of making stuff cheaper so more

176
00:08:16.740 --> 00:08:19.199
products can be made more quickly and

177
00:08:19.199 --> 00:08:21.620
provided to customers at lower prices

178
00:08:21.620 --> 00:08:24.960
without the modern day assembly line our

179
00:08:24.960 --> 00:08:27.000
manufacturing economy would not last

180
00:08:27.000 --> 00:08:30.180
long so what do you think would you

181
00:08:30.180 --> 00:08:32.099
rather be a person who builds something

182
00:08:32.099 --> 00:08:34.620
from beginning to end or one of the

183
00:08:34.620 --> 00:08:36.719
people on the assembly line who adds a

184
00:08:36.719 --> 00:08:39.839
part to it either way there's no turning

185
00:08:39.839 --> 00:08:42.839
back time automated assembly lines are

186
00:08:42.839 --> 00:08:45.120
here to stay and so are the machines

187
00:08:45.120 --> 00:08:48.360
that operate them who knows maybe one

188
00:08:48.360 --> 00:08:50.700
