Question

What are the advantages and disadvantages of mechanical work

Answer 1

Answer:

Mechanical energy is the energy a substance of a system has because of its motion. It is the sum of potential and kinetic energy. So here this article gives the advantages and disadvantages of mechanical energy to better understand this topic.

Advantages of mechanical energy:

• It is one of the most economical to generate, among all types of energy.

• It depends on itself to generate the power, so it is autonomous.

• It is more efficient than manual labor.

• It is a very versatile energy, so it has multiple applications and uses.

• It is more comfortable and safe, the machines have decreased the occupational hazards and the accidents have been reduced.

• This type of energy is easily accessible, its distribution and use are very economical in different sectors.

• It speeds up the process in which a lot of human strength would have to be used.

• The potentially used animal force was replaced by machines.

• The potential of the force to be produced is higher than that exerted manually.

• It affected positively the way the task was performed, reducing manual labor and in other cases anulandolo's complete.

Disadvantages of mechanical energy:

• There is an important cost in maintaining the machines that take advantage of this energy.

• Moving heavy machinery often represents an important cost.

• Traning and or specialization is required for the use of certain machinery.

• Over time, in some sectors machines replace the human workforce creating unemployment.

• The machine is usually heavy, which opens up some risks.

• The transmissions of this type of energy over long distances is complicated.

• Machines may become obsolete over time and require replacement.

• There is greater wear at the thermal level.

• Machines failures continue and represent a cost for repair or replacement.

• The interaction with the machines can be a bit traumatic and complicated for some people.

Answer 2

It depends on itself to generate the power, so it is autonomous. It is more efficient than manual labor. It is a very versatile energy, so it has multiple applications and uses. It is more comfortable and safe, the machines have decreased the occupational hazards and the accidents have been reduced.The advantages of the use of mechanical harvesting machines in the USA were:

 The price of wheat was high and demand limitless. These new machines allowed farmers to quickly clear tracts, break up the soil, remove the grass and prepare the ground for cultivation.

 The work could be done within a shorter time period and with a lesser number of labourers.

 With power-driven machinery, four men could plough, seed and harvest 2,000 to 4,000 acres of wheat in a season.

However there were some disadvantages for the poorer farmers too:

 They were thrown out of their jobs and they lost their means of livelihood.

 Many of them bought this machine too but it adversly affect them as the machines were expensive and once the demand crossed its limit there was enough surplus grain in the market. 

Thus, farmers needed to pay back the loan they had taken from banks to buy these machines, and the farmers

had no money.
