Engineering mechanics is a fundamental course for all engineering students. 

After going through this course (online) they will learn about

Fundamental of statics

Truss and beams

Friction

Centroid and Moment of Inertia

Dynamics of Particle

Dynamics of Rigid body

Detail numerical sessions 

The goal of this Engineering Mechanics course is to expose students to problems in mechanics as applied to plausibly real-world scenarios. Problems of particular types are explored in detail in the hopes that students will gain an inductive understanding of the underlying principles at work; students should then be able to recognize problems of this sort in real-world situations and respond accordingly.

Further, this text aims to support the learning of Engineering Mechanics with theoretical material, general key techniques, and a sufficient number of solved sample problems to satisfy the first objective as outlined above.

As you see in the diagram mechanics is the first and most fundamental branch of physics, supporting Thermodynamics and Electricity, and including Statics, Dynamics(=Kinematics+kinetics); all which are all highly applicable in engineering. But the most important part of them is statics (study of body at rest) which is not only a base for all others, but also have the highest engineering application. Physics also involve optics, waves, quantum, and relativity theory, which have no fundamental engineering application yet.
