Mechanical engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines. The engineering field relies on your understanding of the core concepts involved in mechanics, kinematics, thermodynamics, material science and structural analysis. Mechanical engineers use these core principles along with tools like computer-aided engineering and product lifecycle management to design and analyse manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices and more.
A combined competitive examination is conducted by the Union Public Services Commission (UPSC) for recruitment to the Indian Engineering Services. The Examination constitutes of a written examination followed by an interview for personality test.
Every IES exam is divided into two sections -
Paper I & Paper II .
While paper I remains common for all the branches/streams of engineering, the paper II is specialised with respect to the branch of engineering students.
Indian Engineering Services(IES) include technical and managerial services for government of India. The pay scale of Indian Engineering Services is as high as the pay scale of IAS officers. After 7th pay commission, an IES officer with their esteemed cadre receives more benefits along with high salary and varied allowances and benefits.

The online preparation for IES Mechanical Engineering 2020 by VANI Institute in association with AspireBuzz has been designed by top educators from reputed universities and is available in two packages to the IES Aspirants. The topics are meticulously curated by our proficient and well-experienced senior Professors/Lecturers of Vani Institute across the country identifying the critical topics for subjects from IES assessment perspective. Based on their needs or requirement, an aspirant can choose any suitable package:
This module is designed to help you solve the tests for Online Preparation on IES 2020 Mechanical and understand the concepts associated with the questions provided. AspireBuzz follows the principle of Stimulation Based Learning, an unique interactive module, where the aim is to stimulate our conceptual analysis and reach to the solution on our own rather than the direct answer approach. Each question in this test series is accompanied by three videos:
[Please Note: All the videos are exclusive to Aspirebuzz and VANI Institute and are created by the faculty from premier institutes across the country.]
This package is ideal for students who are already preparing for the UES and are looking towards further robust enhancement in the preparation for IES 2020 Mechanical through online preparation mode. The package comes along with multiple questions for the students to perform and solve. Each question is accompanied with a solution. The solutions available are in a relevant text format in this and so does not contain any videos.
You can very well anytime, anywhere register for a free demo/trial package with our learning platform AspireBuzz and let your journey for Online Preparation of IES 2020 Mechanical begin with a bang.
