This application was made by me years ago using the Director which now are no longer in use. Recently I found it back in my old portable hard drive so I'm thinking to share it. It might be useful to you.

### JJ203: SAND CASTING

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. Over 70% of all metal castings are produced via a sand casting process

There are six steps in this process:

There are six steps in this process:

- Place a pattern in sand to create a mold.
- Incorporate the pattern and sand in a gating system.
- Remove the pattern.
- Fill the mold cavity with molten metal.
- Allow the metal to cool.
- Break away the sand mold and remove the casting.

### I'M MOVING TO POLITEKNIK MUKAH SARAWAK

Dear students and all reader,

Starting from today, i'm no longer a lecturer of

**Politeknik Sultan Mizan Zainal Abidin**. Today is my first day as a lecturer of**Politeknik Mukah Sarawak**. Unfortunately, i'm also no longer teaching mathematics and science because I'm currently attach to new department, the Mechanical Eng. Department... but i'm will never delete any previous contents so anyone still can use it. Thanks for all of your support.

### 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

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:

### AKTIVITI: BENGKEL ASAS ADOBE PHOTOSHOP 2013

Pada hari Sabtu 16/03/2013 yang lalu, Jabatan Matematik, Sains dan Komputer telah menganjurkan satu bengkel asas aplikasi Adobe Photoshop di Makmal Glab1 dan ACAD4. Kepakaran pensyarah JMSK sendiri iaitu En. Abdul Aziz Ikhwan Ab Wahab dan En. Khairul Faizal Abdul Hamid bagi menjayakan bengkel ini. Kehadiran pelajar dari semester akhir (Program Kejuruteraan sahaja) amatlah mengalakkan. Kira-kira 80 orang pelajar telah menghadiri bengkel ini dengan rasa penuh semangat. Rata - rata pelajar menunjukkan minat yang sangat tinggi untuk menguasai asas-asas suntingan mengunakan Adebe Phostoshop ini. Kehadiran Ketua Kursus Matematik Pn. Marina Majid bagi merasmi tutup bengkel ini adalah sebagai wakil kepada Ketua Jabatan JMSK.

### BA202: MATHEMATICAL INDUCTION

**The wikipedia says about mathematical induction:**

**Mathematical induction**is a method of mathematical proof typically used to establish that a given statement is true for all natural numbers (positive integers). It is done by proving that the

**first**statement in the infinite sequence of statements is true, and then proving that if

**any one**statement in the infinite sequence of statements is true, then so is the

**next**one.

The method can be extended to prove statements about more general well-founded structures, such as trees; this generalization, known as structural induction, is used in mathematical logic and computer science. Mathematical induction in this extended sense is closely related to recursion.

## Example

Mathematical induction can be used to prove that the following statement, which we will call

*P*(*n*), holds for all natural numbers*n*.*P*(

*n*) gives a formula for the sum of the natural numbers less than or equal to number

*n*. The proof that

*P*(

*n*) is true for each natural number

*n*proceeds as follows.

**Basis**: Show that the statement holds for

*n*= 0.

*P*(0) amounts to the statement:

In the left-hand side of the equation, the only term is 0, and so the left-hand side is simply equal to 0.

In the right-hand side of the equation, 0·(0 + 1)/2 = 0.

The two sides are equal, so the statement is true for

In the right-hand side of the equation, 0·(0 + 1)/2 = 0.

The two sides are equal, so the statement is true for

*n*= 0. Thus it has been shown that*P*(0) holds.**Inductive step**: Show that

*if*

*P*(

*k*) holds, then also

*P*(

*k*+ 1) holds. This can be done as follows.

Assume

*P*(*k*) holds (for some unspecified value of*k*). It must then be shown that*P*(*k*+ 1) holds, that is:
Using the induction hypothesis that

*P*(*k*) holds, the left-hand side can be rewritten to:
Algebraically:

thereby showing that indeed

*P*(*k*+ 1) holds.
Since both the basis and the inductive step have been proved, it has now been proved by mathematical induction that

*P*(*n*) holds for all natural*n*

*here is another example by me:*

### 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.
