This course serves as a springboard into Engineering Solid Mechanics for new students or as a refresher for students already familiar with some of the concepts and are looking for somewhere to brush up the fundamentals.
The course covers a broad spectrum of common topics that are applicable to a wide variety of situations in numerous engineering sectors;
All of these topics are fascinating and are around the A-level to University level in terms of technical content... but don't worry! We cover these topics in a logical order and start off simple so that we do not lose you along the way. Most videos follow the format of a discussion of the theory and then we go through a worked example. We then recommend that students have a go at the practice questions that accompany most videos so that you can put your skills to the test. There are full worked solutions so you are able to check how you perform.
We at Learn-Ed believe that the format of "Theory - Worked example - Have a go for your self" is one of the best methods of learning - particularly the "Have a go for yourself" element.
We also try to describe various applications that each theory has to help give context as to why its interesting to learn about.
We hope to see you in our lessons!
This video introduces free body diagrams which are a very powerful tool to help visualize problems and will make these problems easier to solve. Moments are also discussed and will provide a useful foundation for the beam bending topics covered in future videos.
This video describes the three laws of motion provided by Issac Newton that help us understand how forces work. We also talk about why stress and strains occur in objects.
This video takes the learning from the previous video further to describe the relationship between stress and strain. We also look at why objects such as elastic bands will decrease in cross sectional area when stretched using Poisson's theory.
Having covered stiffness due to the material parameter known as Young's Modulus, we now cover in this video the stiffness of a component which is commonly referred to as the second moment of area.
This video covers the basic of shear force and bending moment diagrams when loaded simply.
This video covers shear forces and bending moment diagrams in more detail by introducing uniformly distributed loads.
This video covers shear forces and bending moment diagrams in even greater detail by couples.
This video describes the types of stresses we see in a beam when loaded and terms such as the neutral axis or neutral layer.
This video covers one final important bit of theory that can be very useful to engineers - how much a beam might deflect when put into bending.
This video introduces a couple of theories that model the inelastic stability of columns when axially loaded in one of several arrangements.
This video describes what happens to objects when subjected to varying temperatures and why it is useful.
This video introduces a powerful theory in allowing students to analyse seemly complex structures quickly and easily.
This video shows how shear loads are subtly different from comprehensive and tensile loads, though shows how solving problems are very similar.
This video introduces a forth fundamental type of loading - torsion. Torsion occurs often in the world and we discuss an equation that can help us obtain a lot of information about any problem we may encounter that involves torsion.
This video provides an introduction to the vast topic that is pressure vessels. Here we cover thin walled pressure vessel which is a good starting place to this complex and in depth topic. In this video students will begin to gain an appreciation at just how many pressure vessels there are in the world.
Learn-Ed is formed from two professionals each with Masters Degrees in mechanical engineering and each have experience in high profile professional jobs in the automotive and defense sectors. These two professionals also have a wealth of knowledge in non-engineering topics and aim to build a collection of courses to help students become skilled in a wider range of subjects.
