Key Topics in Upcoming GATE February 2019 - Mechanical Engineering

In preparing for the GATE (Graduate Aptitude Test in Engineering) Feb 2019, mechanical engineering aspirants can focus on certain critical areas that have historically carried significant weight in the exam. By understanding and preparing these topics thoroughly, candidates can enhance their chances of success. Here we outline the crucial sections based on the mark distribution in previous GATE exams.

Engineering Mechanics

(Marks: High)

Engineering Mechanics is consistently among the most important topics for the GATE exam. This section delves into the fundamental principles of forces, moments, equilibrium, and kinematics. These concepts are foundational and frequently appear in the exam. Effective strategies include studying the laws governing translational and rotational motion, mastering the analysis of static and dynamic systems, and practicing numerical problems related to forces and moments.

Thermodynamics

(Marks: High)

Thermodynamics is another crucial area, covering energy transfer, heat transfer, and the laws of thermodynamics. A deep understanding of the first and second law of thermodynamics, and the ability to apply these principles to real-world problems, is essential. Candidates should focus on entropy, internal energy, and the analysis of thermodynamic cycles. Practice problems involving the calculation of thermodynamic properties and the use of thermodynamic charts are particularly beneficial.

Strength of Materials

(Marks: High)

This topic focuses on the behavior of different materials under various loading conditions. Understanding concepts related to stress, strain, and deformation is crucial. Candidates should study the principles of elasticity, plasticity, and fracture mechanics. Practice problems involving stress analysis, strain gauge experiments, and material testing are highly recommended. Additionally, knowledge of failure criteria (such as the maximum principle stress criterion and the maximum shear stress criterion) is vital.

Machine Design

(Marks: Medium-High)

Machine Design requires a thorough understanding of the design principles of machines and mechanical components. Key areas include gear drives, bearings, power screws, and design for static and dynamic loading conditions. It is essential to practice drawing and analyzing mechanisms, as well as understanding the influence of various loads on these components. Familiarity with fatigue strength, wear, and lubrication is also important for success in this topic.

Fluid Mechanics

(Marks: Medium-High)

Fluid mechanics involves the study of the behavior of fluids both in motion and at rest. Topics such as fluid statics, fluid dynamics, Bernoulli's equation, and boundary layer theory are critical. Candidates should focus on comprehending the principles of fluid flow, pressure distribution, and the application of Bernoulli's theorem. Additionally, understanding concepts related to turbulence, flow through pipes, and external flow (such as boundary layers) will help in excelling in this section.
