Mechanics

Mechanics is about the study of forces, energy, and movement.  It is the same discipline as what is taught in the first year Mathematics syllabus, but in these notes, I apply it more in the context of Physics.  Many concepts in engineering are based on what we will learn here.

 

We will look at how forces act, especially in equilibrium - important in structures. 

We then go on to look at moments and consider their significance in bridges and stability.

We will look at motion in a straight line, and consider Newton's Laws of Motion.  These were written 350 years ago, but are just as valid today as they were then. 

We then go on to motion in a gravity field, including free fall, terminal velocity, friction, and drag.

We will look at the concepts of momentum, and how it can be used to explain what happens when balls are struck, collisions, and explosions. 

We then go on to consider how work is done when a force is moved, then move on to efficiency and conservation of energy.

It will also make very good lavatory reading.  Knowing where a formula can be found will help you no end in the exam.
