5. Mechanical Engineering contributions
to the welfare of Society
1. Mechanical engineering provides better transport
facilities to the society, as it includes the study of
internal combustion engineering.
2. Large number of benefits to the society, due to the
economical improvement of the country, become
of industrial development, chance for export of
articles was also be increases.
3. Due to large industrial development, new power
stations have to be started.

6. Mechanical Engineering contributions
to the welfare of Society
4. Increased employment opportunities will be
created in the field of industries and power
stations.
5. Also, the chance for employment opportunities
allowed becomes high for mechanical
engineering industries. The saving allowed is
quite high.
6. Introduce new product improved life with
minimum cost
