Mechanics (Understanding and Working with Machines) 100 Hours Certificate Course
Learn About Mechanics (Machines)
Mechanics Course Online: Learn the mechanics behind the maintenance and repair of machinery. This distance learning course is not only relevant to cars. It is relevant to any machine with an engine or a motor, including those found in the home. Gain an understanding of how machines work, so that you can undertake servicing and repair jobs yourself.
This is an ideal course for DIY Enthusiasts and a great foundation programme for apprentices either working in or wanting to work in the service and repair of cars, farm machinery, home appliances, lawn mowers and many others.
Machines have become so much a part of modern life that we can easily take them for granted. Most people don’t even give a second thought to how the machines they use are functioning; that is until they stop functioning.
Learning more about mechanics can enable you to do so much more with machines though, from using them more appropriately and safely to maintaining and repairing them when required. Some machinery is relatively simple and easier to learn about, but other machines can be much more complex and will require far more learning and experience to properly understand.
This course is the cornerstone for understanding and working with all machines, each lesson building upon what you learnt in the previous ones, gradually expanding your awareness and understanding of how and where engines can be used to power machines, and how different types of machines function.

Practical (Set Tasks)
THE LUBRICATION SYSTEM
Any piece of metal, regardless of how smooth and polished it may look to the sight or touch, is covered with tiny irregularities and projections. When two highly polished metal surfaces are brought together, and one forced to slide over the other, the projections grip each other, causing resistance to the sliding.
This resistance is called FRICTION. Friction results in wear of the metals. The amount of friction depends on the type of material, amount of pressure and the nature of the surfaces.
Lubrication reduces friction, and this occurs when some substance, either liquid or solid is put between two rubbing surfaces. Lubrication also reduces wear and heat that would otherwise occur. The lubrication system must distribute the lubricant so that at no instance is there metal to metal contact in any moving parts.
There are different types of lubrication systems, for different types and sized engines, e.g. the splash feed system (see diagram below) and the force feed system. Although the lubricant acts as a coolant, some sort of cooling system is also necessary in an engine (cooling methods are discussed in the following section).
Oil contamination can occur so it is necessary to change the oil regularly, after a certain number of operating hours. Moisture contamination can occur in an engine due to condensation and also as a result (by-product) of the cooling process itself. Dirt may enter through the air intake of the engine, so it is important to regularly change or maintain the air filter. Tractors, particularly, operate in very dirty environments and for this reason they are fitted with a special mechanism called an oil bath air cleaner. Carbon and soot by products also cause oil contamination.
The Cooling System
When a motor or engine is operating it produces a significant amount of heat. To prevent damage to the engine it is necessary to keep the engine at a correct temperature. Operating an engine at overly high temperatures causes structural damage to engine components, and overly cool operating temperatures mean the fuel will not vaporise properly. The two main methods for cooling engines are air cooling and water cooling.
Air cooling is mainly used in small engines (single cylinder) or for machinery like potato harvesters, lawn mowers and elevators. A blast of air is directed on the cylinder and cylinder head, both of which are finned (see diagram below). These fins increase the surface area of the cylinder and provide a larger surface area through which the heat can spread. Air cooled systems are simple and reliable, but are less efficient than water cooled systems as air has a lower heat capacity, so more air is needed to produce the same effect as water. Over-heating can occur if the fins become blocked with dirt, as this reduces the surface area to be cooled.
Water cooling is more effective for use in multi-cylinder engines. The engine cylinders are completely surrounded with a water jacket. The water extends to the cylinder head where there is an outlet to the radiator. There is another outlet at the bottom of the radiator connecting back to the water jacket surrounding the cylinders. Water flows around this system.
The radiator is composed of a head tank and a bottom tank. Between these there are a lot of thin tubes and metal plates that greatly increase the surface area to be cooled. This is the core of the radiator. Behind the radiator core there is a fan that operates via a pulley system connected to the crank shaft of the engine. This fan blows cool air onto the radiator. The cooled air circulates back through the engine.
Assessment is based on a combination of completing all assignments and sitting for a final short one and a half hour exam, in your own location.
If you don’t cope well with exams then you may elect to undertake a project instead. This is a popular option.
In addition, most modules have a Set Task at the end of each lesson placed before the assignment. This is an opportunity to undertake practical work to help you acquire knowledge and skills and practical experience. This ADL feature is an added bonus not found at most online schools. Set Tasks are not required for assessment.
Some courses also have optional Self-Tests which are available on our online learning platform. These are not available by correspondence or by USB, and do not form part of your overall grade.
How our courses work
- Choose Your Learning Method
You choose how you would like to receive your course material, i.e., Online, USB or Correspondence. The choice is yours. You may also work on online or offline.
- Tutor Allocation
Every student is assigned their own dedicated tutor who is an expert in their subject area. They provide as much or as little individual contact as you require. You can contact your tutor whenever you need – your hours are not limited.
- Feedback and Assignments
Tutor Feedback is an essential component in helping you understand the subject matter. Tutor feedback is given in the form of notes written on the assignment. We encourage you to contact your Tutor where help with clarification and understanding of course material may be required.
Your assignments are located at the end of each lesson. You submit them for marking whenever you are ready. There is no time limit.
- Set Tasks and Self-Tests
Most modules have a Set Task at the end of each lesson before for the assignment. This is where you get the opportunity to undertake practical work to help you acquire knowledge, skills and practical experience. Many modules also have short Self-Tests.
Once all assignments have been completed you may then elect to sit for a one and half hour exam in your own location. If you prefer not to take the exam you do have the option to undertake a project instead.
Once the exam or project part of the course is completed, your Certificate is then processed. Please allow approximately 4 weeks for this.
- Design Your Own Qualification
ADL offers students the flexibility to self-design their own qualification – bundling together a combination of 100-hour modules into a qualification higher than a certificate.

Q. Assessment – how does it work?
A. For each 100 hour module you are assessed by assignments (at the end of each lesson) and a final one and a half hour exam (or you may elect to complete a project instead of sitting the exam) – the choice is yours – you sit for the exam in your own location, or you can visit us in Canterbury, England to sit the exam if want to. Exam fees are included in the tuition fee you paid. You can read more about the examination process here. At the end of each lesson, there is an assignment. You submit it to the academy who then submits it to the tutor for marking, comments and feedback. Our policy is to have a grade for you within 5 to 7 days.
Q. How many assignments do I need to complete for each module?
A. At the end of each lesson, there is an assignment – so if a course has say, 10 lessons there would be 10 assignments. The number of lessons per module varies from module to module. See the course content from our website for further details.
Q. When do I have to hand in my first assignment?
A. There is no deadline for handing in the first assignment. Submit when you are ready. There are some students who hand in assignments within the first couple of weeks of enrolment – while there are others who submit their work 6 months later. It’s all at your own convenience to suit you. Everyone has different work and home commitments and we cater to these needs.
Q. I am having difficulty attending workshops/industry meetings, what can be done?
A. If your course requires attendance at workshops, conferences, or industry meetings; alternative arrangements can be made in your country; however, there may be an additional expense. We can appoint an appropriately qualified person anywhere to work through curriculum documentation supplied by us, to satisfy the requirements set down in a course.
