Mechanics, a name I've given to describe the domain of the mechanical engineer, is an extremely broad field that covers just about everything that isn't electricity or software; Mechanims, hydraulics, pneumatics, aerodynamics, combustion, refrigeration, even classical optics are all disciplines that fit well within the umbrella of mechanics.

A mechatronics engineer must be familiar with the basics of all of these areas; they provide a large pool of options for a design.


Mechanics is a branch of physics that helps engineers to design products that perform correctly and reliably.

What is force?
Forces cause objects to accelerate and deform.
What is gravity?
Gravity is the most familiar cause for acceleration in the human experience.
What is Friction?
Friction impedes the acceleration of objects and brings moving objects to a halt.

Simple Machines

Simple machines are the elementary building blocks from which most real products and machines are made from.

Mechanical CAD Software (MCAD)

Mechanical CAD software (MCAD) is used in the design of almost every product manufactured today.

Mechanical CAD Software for Hobbyists and Garage Startups
This is a free trial article. Mechanical CAD software is used to design every object manufactured today; from toasters to rockets.


Robots are complex electromechanical machines for automating tasks. They have immense potential (both for good and bad).

Introduction to Robotic Actuators
Robotic actuators are electromechanical devices with a lot of parts.
The Bang-Bang Motion Profile
The bang-bang motion profile is the time optimal motion profile for point-to-point motion.


Manufacturing, the science of making things, is also an art. Without manufacturing, we wouldn't have any of the modern conveniences we enjoy today.
