Mechanical Engineering


Spur gears

Gears are used to transmit power (product of torque and rotational velocity) from one location and form to another.

Mechanical engineering is an extremely diverse field, and is one of the mainstays of product design engineering. Brainchild’s expertise is mainly concentrated within the following fields:


Statics is the core of mechanical engineering. It is focused on the study and characterisation of forces (internal and external) present in physical objects. Fundamental phenomenon such as force, pressure, friction, deformation, and moment/torque are factors which affect all physical objects and must be understood and quantified if a product design is to function.

Once basic function has been achieved, the next most important goal of structural engineering (aside from safety, which is always first) is to find ways to create structures that have a high strength to material ratio. It’s easy to throw together a massive, thick structure design that does not break. But ultimately, this is nothing more than “throwing money at the problem”; Without engineering optimization, money is wasted because forces and materials are not distributed efficiently. The job of a Brainchild mechanical engineer is to make sure your design not only works, but is as lean and inexpensive as possible to produce.

Dynamics (kinematics and kinetics)

Kinematics is the study of pure motion. Kinetics is the combination of forces with motion (what causes motion); It can be summarized by Newton’s 2nd Law (f=ma). Naturally, this field of study is most important for products with moving parts, such as gears, pulleys, bearings, etc. Design of mechanisms is a field of study wherein available forces are optimized to produce as much of a desired outcome as possible (force, speed, acceleration, etc.).

There’s always another way to do something!



The gyroscope is an engineering marvel that appears to defy gravity.

Thermal and Fluids

While thermal and fluid sciences are two disctinct categories, they overlap in many ways. For example, convective heat transfer is a phenomenon which relies upon fluid motion (e.g. a furnace blowing hot air into a cold room). While theoretical models lay the foundation for fluid sciences, the field is greatly accelerated by CFD (computational fluid dynamics), which uses an interative approach to simulate complex scenarios that would be practically impossible to solve for by hand.

Brainchild Engineering utilizes SimScale as one tool to perform CFD and thermal studies.
