# Engineering Mechanics Books

We have updated the Books and Study Materials for the first year Engineering. Candidates can download the files in Pdf format in the official website. Earlier we had updated many Books on Engineering on the web. Candidates can choose the subject they want to study from it and download in pdf. In this article, we are going to talk about Engineering Mechanics. Mechanics is the department of science which deals with the behavior of objects at rest or in motion, under the control of forces. Engineering mechanics includes the application of the principles of mechanics to solve real-time engineering problems.

# Engineering Mechanics Books 2018

It is the study of forces that act on bodies and the resultant motion that those bodies feel. This Engineering Mechanics course aims to present students to problems in mechanics as applied to reasonably real-world scenarios. Issues of particular types are investigated in detail in the hopes that students will gain an inductive knowledge of the underlying principles at work. The examination of these subject is quite competitive. To prepare yourself for the exam we have provided the necessary Books and Study Materials which will help you at the time of preparation. We are also giving the detailed syllabus of the subject so that you can follow it and the learning process will be natural.
