With the ongoing Covid-19 pandemic, businesses have shifted their operations to online platforms while people have been forced to resort to work-from-home lifestyles to prevent the further prevent the spread of the virus.
Additionally, the current era of digital revolution along with advancements in technology integration has brought several industries closer together, pushing their inter-dependence forward to create a symbiotic relationship within various sectors.
Revolutionary industry changes along with the severe decline in available opportunities during this period have caused major impacts on graduates worldwide.
The attempts to cut back on operational costs have created a cutthroat competition to be part of the workforce within several sectors and employers have established higher and more refined requirements from their younger working professionals.
They are also required to be able to possess great problem-solving and analytical skills, communication skills, management skills, and the ability to work in different teams.
Over the years, one of the fields that have been majorly affected is the field of mechanical engineering.
Considered one of the oldest disciplines in engineering, it is also the broadest due to its amalgamation of civil, chemical, and industrial studies.
Hence, it is a popular study of choice as graduates in this field are often found in varied work settings spanning several industries and are in high demand due to rapid industrialization.
Mechanical engineering is no longer limited to a niche field and has descended into several other specializations that include CAD/CAM, AI & ML, IoT, etc.

Here are the new trends in mechanical engineering that aspiring engineers should know about:
CAD/CAM are software that use computer-based methods to encode geometrical data in which the processes of design and manufacture of automated machinery are highly integrated.
While CAD is mainly used to create designs, CAM is the control of machine tools in the manufacturing of parts.
The former helps designers and the latter helps reduce manufacturing costs. Both the software require powerful computers.
Heat exchangers are systems that work by transferring heat from one place to another between two or more fluids.
It is a system that facilitates heat transfer in an easy way without actually transferring the fluid directly. They are highly important parts of fuel cell systems for thermal management functions.
The mechanical engineering field has recently seen a lot of scope in designing energy-efficient, effective, lasting heat exchangers.

Smart manufacturing, easily put, is a manufacturing system that could have speed, structure, and accountability to resolve issues, to bring about a completely integrated, collaborative structure across all ends of the supply chain.
It ensures a real-time response, to meet the ever-growing demands in customer needs and the changing conditions of the supply network. It is called Industry 4.0 as it is the fourth industrial revolution in which the idea of smart manufacturing comes.
This smart industry has helped improve product quality, improve your asset utilization, etc. along with IoT, which is an interrelated system connecting devices, mechanical machines, people, objects, etc. to help transfer data over a network using UIDs (Unique Identifiers).
AI is the technology where a machine tries to simulate human behaviour. It is most definitely the future of every industry as AI is being used in most up-and-coming technological fields like robotics, VR, IoT, etc.
Machine Learning is one of the applications of AI which provides the system with automatic knowledge about a machine without having them explicitly programmed beforehand. ML also helps applications make better prediction outcomes.

Currently, some of the major industries recruiting for mechanical engineers include those involved in the fields of automobiles with hybrid and autonomous technology, data sciences, embedded systems, smart cities and urban analytics, etc. other than the above mentioned.
The future of mechanical engineering looks bright as several industries now require individuals with a strong sense of analytical skills and a deep understanding of evolving technologies in order to keep up with existing trends and set new standards in the industry.
