In the context of the cp online learning environment, an electronic space where course participants can record observations, opinions and feedback as well as their thoughts and feelings about how they have been instructed in the past, and how they learn.

Course participants means everyone involved in the site, or directly on the course: apprentices, instructors, employers, managers, lecturers from phase 4 and phase 6, researchers and students of education, qualified cp fitters, secondary school career guidance teachers and parents of apprentices.

The learning journals are strictly confidential. Any one using the journals is guaranteed strict anonymity. Your comments are gathered for formal research purposes, and your name is never associated with your comments. Any research work is guided by a strict code of ethics. For any particular research work, there is always an ethics statement available to all participants.

All opinions are welcome, positive and negative, good and bad. All that is asked is that they are honest and constructive.

All research conducted in the CP Section has one main goal: to improve the learning experience for each apprentice. To do this, we have to better understand how each apprentice learns, and how we can help them as they learn.

Read a little more about learning journals here, and see how past apprentices used them.


Megabyte: a million bytes.

This can refer to different things:

When used thus: "A 500 Mb hard disk", it means the hard disk has a capacity of 500 Mb - it has room to store 500 megabytes of information.

When used thus: "This machine has 256 Mb RAM", it means that the computer is equipped with 256 Mb of Random Access Memory.


Mega is a prefix used to denote a million. For example:

A Megabyte is a million bytes.

Check here for more on prefixes.


When used in the context of electricity and electrical caclulations, intensity refers to the amount of electricity flowing in a cirucuit.

For example using Ohm's law, we can calculate the power of a circuit by mulitplying the current by the voltage: W=I.V,

or we can calculate the resistance of a circuit by dividing the voltage by the current: R=V/I

μ mu, from the Greek alphabet. Used on the cp course to represent the co-efficient of friction.

The co-efficient of friction is calculated by dividing the horizontal force (H) necessary to keep an object moving on a surface, by the downward force (D) exerted by that object.


Check here for more information.

Greek letter used to represent resistance in electrical circuits.

π Greek letter used to represent how many times the diameter of a given circle will fit into its circumference. This is constant at 3.142. Apprentice cp fitters use this figure for many calculations, for example: when calculating the capacity of an engine; when calculating centrifugal force and when calculating the peripheral speed of a cutting disk.


In scientific calculations on the course, g represents the acceleration produced in a falling object by the effects of gravity.

An object falling toward the ground will accelerate at the rate of 9.81 metres per second, for every second that the object is falling.
This is represented by: g = 9.81m/s/s or 9.81m/s2

Apprentices will use this figure when calculating the weight of an object, given its mass.

For example, to calculate the weight of a 10 tonne machine, we convert the 10 tonne to the base unit of kilogrammes, 10,000 Kg. This is the mass of the vehicle. To calculate the weight, we use the following formula:

W = m x g

W = 10,000 x 9.81

W = 98,100 Newtons, or 98.1KN

Objects dropped on the earth, regardless of their weight, will fall to the ground and hit the ground at the same time. So, in theory, a cannon ball and a feather dropped together, would hit the ground together. Of course, on earth, the atmosphere would distort this experiment. However, on the moon there is no atmosphere to interfere. Even though the moon's gravitational field is only about 1/6th of that on earth, if the theory is correct, the hammer and the feather should hit the ground at the same time.

There are many Institutes of technology around Ireland. The one of interest to the apprentice cp fitters is in Cork, because that is where they will receive their phase 4 and phase 6 training.

There are 7 phases of training for CP Fitters. Phases 2, 4 and 6 are "off the job" and delivered in the FAS training centre, Cabra (phase 2), and the institute of technology in Cork (phases 4 and 6).

Phase 2 is of 20 weeks duration, and phases 4 and 6 are of 10 weeks duration each.

Phase 1, Phase 3, Phase 5 and Phase 7 are delivered "on the job" in the apprentices' place of employment


Courses that run on this website may require an enrolment key for entry. The purpose of the key is to ensure that only registered participants can access courses.

If you are a registered user, simply email us with your request, and we will send the enrolment key to you.
