mechanical, electrical and instrumentation engineering for non-engineers
DESCRIPTION
You will learn the basic applied concepts of mechanical, electrical and instrumentation engineering in this workshop. This will enable you to work more effectively with your engineering colleagues – no matter whether they are operators, tradespersons, technicians or engineers. There are three main threads running through this course – initially mechanical engineering, then electrical engineering best practice and concluded with instrumentation (or industrial automation). Mechanical engineering in simple terms deals with any equipment that moves; this is what makes it perhaps the most broad and diverse of engineering disciplines. The mechanical discipline essentially derives its breadth from the need to design and manufacture everything from small, even nano, individual devices, such as measuring instruments, to large systems such as machine tools and power plants. The focus in electrical engineering is on the building blocks of electrical engineering, the fundamentals of electrical design and integrating electrical engineering know-how into the other disciplines within an organisation. Unnecessary theory will be minimised. The dangers and risks from electrocution, shock, explosions and arc blast can never be eliminated but you can take definite steps to protect yourself and your co-workers. The topics in instrumentation engineering commence with an introduction to instrumentation and measurement ranging from pressure, level, temperature and flow devices followed by a review of process control including the all important topic of PID loop tuning.

Force
• Force: A push or pull on an object resulting from its interaction with another object.
• The unit of a force is Newton [N].
5 m
45°
100 N

Force• Equation F = ma gives the relationship between:
– Force (N)– Mass (kg)– Acceleration (m/s2)
– Also known as “Newton’s second law of motion”.

Work
• Defined as “force through distance”.
• In other words–“ when a body moves under the influence of
a force, work is done”.
work = force x distance–The unit of work is Joules.

Energy• Energy may be broadly defined as the ability to do
work.
• Energy cannot be created or destroyed.
• We merely change energy types, e.g. convert potential energy into kinetic energy.
• The unit of energy is Joules.

Different Energy Forms
• Potential energy: Energy stored in a system, typically due to its height, but others include springs, pressure, chemical, heat etc.
• Kinetic energy: Energy possessed by a body by virtue of its motion.

Isometric and Oblique Projections
isometric projection of a cube
oblique projection of a cube
• Isometric drawings: The two axes are at 60° to the vertical axis, and the measurements along these are either a scale of (or equal to) those measurements on the actual object.
• Oblique drawings: the two axes are at right angles to each other, and the third axis is at 45° to them.

First-Angle Projection• Three views:
• Front view: Drawn looking straight at the front of the object.
• Side view: The left side of the object is drawn toward the right side view of the object and vice versa.
• Plan View: The top of the object is drawn toward the bottom view of the object and vice versa.
• Used mainly in Europe.

Sectional Views
• Sectional views are used to clarify interior or hidden details on a multi-view drawing of an object.
• For a sectional view the observer is required to imagine that the object has been cut by a plane (the cutting plane) and that the part of the object nearest to the observer has been removed.

Dimensions• Dimension: A means of specifying the size of a
part, such as its length, diameter, width and thickness.
• All dimensions required for manufacturing and assembly must appear on detail drawings.
• Nominal dimension: the size by which a part is referred to as a matter of convenience, or the size on which the design is based.
