BB101: ENGINEERING SCIENCE WORKBOOK

Engineering Science Workbook for Malaysian Polytechnics was an effort of a group of experienced lecturers of Politeknik Sultan Mizan Zainal Abidin of Dungun, Terengganu. The workbook was specially written to compliment the BB101 Engineering Science Course which taught in all Malaysian Polytechnics. A research has been conduct before initiate the writing process so the content of the book will cater the needs of polytechnic student. A groups of very competent lecturers which experiencing not less then 7 years was gathered  to design this book.

The book compiling the essence for every topics and come with 20 questions each topic for student test their comprehension. If interested to have this book, please contact:

BB101: ELECTRIC RESISTIVITY

Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm⋅metre (Ω⋅m) although other units like ohm⋅centimetre (Ω⋅cm) are also in use. As an example, if a 1m×1m×1m solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1Ω, then the resistivity of the material is 1Ω⋅m.

Resistors or conductors with uniform cross-section

A piece of resistive material with electrical contacts on both ends.

Many resistors and conductors have a uniform cross section with a uniform flow of electric current and are made of one material. (See the diagram to the right.) In this case, the electrical resistivity ρ (Greek: rho) is defined as:

where

R is the electrical resistance of a uniform specimen of the material (measured in ohms, Ω)

 is the length of the piece of material (measured in metres, m)

A is the cross-sectional area of the specimen (measured in square metres, m²).

The reason resistivity is defined this way is that it makes resistivity a material property, unlike resistance. All copper wires, irrespective of their shape and size, have approximately the same resistivity, but a long, thin copper wire has a much larger resistance than a thick, short copper wire. Every material has its own characteristic resistivity—for example rubber's resistivity is far larger than copper's.

In a hydraulic analogy, passing current through a high-resistivity material is like pushing water through a pipe full of sand, while passing current through a low-resistivity material is like pushing water through an empty pipe. If the pipes are the same size and shape, the pipe full of sand has higher resistance to flow. But resistance is not solely determined by the presence or absence of sand; it also depends on how wide the pipe is (it is harder to push water through a skinny pipe than a wide one) and how long it is (it is harder to push water through a long pipe than a short one.)

The above equation can be transposed to get Pouillet's law:

The resistance of a given material will increase with the length, but decrease with increasing cross-sectional area. From the above equations, resistivity has SI units of ohm⋅metre. Other units like ohm⋅cm or ohm⋅inch are also sometimes used.

Eksplorasi Peta Minda Sains Kejuruteraan

On Saturday 23.02.2013, Department of Mathematics, Science and Computer  PSMZA has organized a programme to help student in their study respectively in making a short or summaries  note from lecture note. As many of 140 junior student admitted to this one day program, they have participate with a lot of excitement and fun during the activity of making their own mind map. This program has been conducted by Mdm. Noor Rulhanim Ariffin and helped by others lectures as facilitators.

 

BB101 : FINDING THE RESULTANT OF NUMBERS OF FORCES

Adding 2 forces are quite a simple things, but this simple thing is also can be use to determine the resultant of numbers of forces acting on a point. Those forces known as the polygon of forces because we can redraw the forces as a polygon. Here is an example how to calculate the resultant and direction involving the process of resolving and resulting.

BB101: EXAMPLE FOR ADDING TWO FORCES

BB101: Adding Forces as Vectors

How to add two forces acting onto a point but in a different  direction and plane?

As we know that forces are vector, so we cannot adding or subtracting them like the scalar magnitude, therefore we have to use the triangle law or parallelogram law to determine the resultant. Please watch the video below to enhance your knowledge.(This video is a copyright of Lucid Education)
