Solid mechanics is an essential part of the branch of physical science that covers the motion and deformation of continuous solid media with applied external loadings such as displacements, forces, and accelerations that lead to inertial force in the bodies, electromagnetic forces, chemical interactions, thermal changes, and so on. Solid mechanics is an essential topic for important entrance exams like Engineering Exams.

This article covers information on the Solid Mechanics syllabus for GATE CE, Solid Mechanics for computer science and detailed Solid Mechanics GATE notes. There are also many Solid Mechanics MCQ PDF and Solid Mechanics online test available to study in-depth the subject of solid mechanics.

Why prepare Solid Mechanics from BYJU'S Exam Prep?

BYJU'S Exam Prep is one of the best websites to find Solid Mechanics study material for GATE CE. All the details about Solid Mechanics notes for CE and Solid Mechanics quiz are easily accessible from BYJU'S Exam Prep. The teachers designed a specialized study plan to cover all topics of Solid Mechanics. All the study materials available are easy to understand and well presented for the students to plan and prepare a checklist to do it sequentially. There could be a question about the topics of Solid Mechanics in the general category too. Students can solve Solid Mechanics online quiz in the study material given by BYJU'S Exam Prep.


Q. Where can I find previous years solved exam papers?

There are many sources online where you can get solved question papers from previous years. The website of BYJU'S Exam Prep also has a lot of different quizzes and question and answer sets to solve.

Q. What is the best strategy to study for Solid Mechanics for GATE?

The student can attend classes with their regular college to prepare better for GATE as the subjects are the same as the college. It will be a good idea to prepare for both together.

Q. Is it possible to score good marks just by preparing some topics or chapters?

No, you must have a thorough knowledge of the whole subject, because the topics are interrelated. So to understand one concept, the student needs to know the other topics well from other chapters.

Q. Why is the variation of shear strain with radius linear?

This emanates from the fact that the cross-section rotates as a rigid body because of the axis symmetry condition of the cross-sectional geometry and the torque's anti-axis symmetry. Since the cross-section rotates as a rigid body, the amount of rotation is linear concerning the variation in radius.
