what are machine operated devices? discuss the advantages and limitations of machine operated devices.
Answers
Advantages commonly attributed to automation include higher production rates and increased productivity, more efficient use of materials, better product quality, improved safety, shorter workweeks for labour, and reduced factory lead times. ... Worker safety is an important reason for automating an industrial operation.
Use of Natural Forces:
Machinery has harnessed the forces of nature in the service of man. Man can fly in the air; he can send messages thousands of miles away; he generates electricity from waterfalls. All this he has done with the aid of machinery. For such jobs, the use of machinery is indispensable.
Heavy and Delicate Work:
Tasks which are too heavy or too delicate for human muscles to do can be done easily by a machine. A crane can lift loads which man never can. No man can produce silk as fine and delicate as a spider’s web, but a machine can. Without the aid of machinery such jobs would not have been done.
Faster Work:
While man can make only a few dozen pins in a day by himself, with the help of machinery he can make thousands. A charkha cannot spin as much yarn in a year as a spinning machine can in one day. We value machinery for the speed with which it works, and in the modern world speed matters the most.
More Accurate Work:
No painter can paint exactly the same picture twice. But a machine can turn out thousands of identical articles. Production has thus been standardized. Only machines are capable of mass production.
Strain on:
Human Muscles Relieved. The work of the labourer has become much lighter.-He has simply to press a knob, and lo! the machine starts working! Thus machinery has proved an great blessing to the workers.
Cheap Goods:
The-use of machinery has resulted in large-scale production and has reduced costs to levels never dreamt of before. Thus cheap goods have been placed in the hands of consumers. A man of ordinary means can now enjoy goods and services which were not available even to a rich man in the past. Consequently the standard of living has risen.
