THE QUESTION:
prove that (2/10)= 2

1.art student :"this is out of syllabus !!!"

2.commerce student : "this is absolutely wrong"

3.medical student : "it is strange...how is it possible?"

4.the engineering student : "it is easy"

(2/10) = (Two/Ten)
*letter 'T' is common. hence,

= (wo/en)
*now,
letter w=23rd letter in alphabet,
letter o=15th,
letter e=5th,
letter n=14th.

rewrite the equation. (wo/en)= (23+15)/(5+15)
= (38/19)
= 2

Engineers are never worried for,

"That is ENGINEER !"

### PRECAST BUILDING STYLE

Nowadays, precast concrete had become a famous construction method around the world. Precast concrete is the casting of concrete in which its process of mixing, placing, and curing is done in factory controlled. It is famous due to its advantages during the construction. There are a lot company around Malaysia which provides a precast concrete section with various types and sizes. Some of the sizes are also being ordered on specific demand by the project engineers.
There are some of advantages of using a precast concrete. Firstly is on the basis of time consumption. Constructions which were using the method of cast in-situ will took a long duration to finish the project due to the time needed for the concrete to dry. For precast concrete, the concrete component had been cast in the company and just being merged in the construction site. Secondly, precast concrete can reduce the cost of construction. This is because the repetitive of standard units sizes. Furthermore, the product which cast in factory has a higher accuracy as compared to cast in-situ. Besides, precast concrete will not be affected by the bad weather which can reduce the strength of concrete. In addition, precast concrete can save the place of storage in construction because the component of precast concrete will be assembled after the components arrive to the construction site.

This is my last assignment for autocad lab conducted by. Mr Norzaidi. its quite interesting to learn this skills of drawing because it is enjoyful and easy to understand. in addition, it helps me to release my tension due to many obstacles in other subject. i will try to learn how to sketch 3d drawing during my upcoming holidays. insyaAllah...

Have a nice day everybody. 11 days to my first final paper, emath2. as a proper preparation, i need to assume library as my second house. just for this week. dont worry, thanks to dr Saiman Mat Baok for teaching me this paper. It quite hard as he said in his class,"engineering subject is easy but math is difficult because it was a language for all engineering and other subjects... im just believe in his words:> hopefully my friends do lots of exersizes as to face the upcoming test. be focus as my friend beside me in this picture. Lastly, built your patience, u will be strong...

Assalaamualaikum and have a good weekend to all of my friends. I am happy that we had reach towards the end of our semester. There are lots of experience and knowledge that i got from my lecturers and my friends. High appreciation to my lecturers, Mr Mokhtazul Haizad, Pn. Syarifah Anom, Mr Norzaidi, Dr Saiman and Mr Sivayogam for teaching me lots of knowledge in many aspect of engineering. At first this blog was created as to accomplished the assignment given by Mr Mokhtazul Haizad but at last i think this blog will be useful in the next coming semester as to guide other future engineers in unisel. Hopefully i can score for this semester and joined the elite group for the next semester. gud luck to all of my friends. together we achieve our goals for this semester. thank u.

### STRESS AND STRAIN- DIRECT STRAIN

Strain symbol can be represented by,

If a bar is subjected to a direct load, then it will change its length. If the original length, L changes in its length by small changes, then the strain produced is:

Strain is thus a measure of the deformation of the bar and is dimensionless. Generally, the magnitude is so small that it is normally stated in microstrain. Alternatively, strain can be expressed as percent (%):

### STRESS AND STRAIN- DIRECT, NORMAL OR AXIAL STRESS

STRESS can be represented by symbol.

Normal stress results from a uniformly or equally applied direct force across a cross section. This definition is illustrated in figure below:

The load P causes the cylinder to increase in length. At equilibrium, the internal force P will be produced at a cross-section x-x as shown in figure above. The stress may be compressive or tensile depending on the nature of the internal forces and are measured in units of newton per square metre.

Normally, tensile stress is taken as positive value while compressive stress is negative value.

Before any engineering structure can be used, we have to ensure that it is able to sustain the load acted on it throughout its life. If the components or members are in equilibrium, the resultant of the external forces will be zero.

If a cylindrical bar is subjected to a direct pull or push along its axis as shown in figure below, then it is said to be subjected to tension or compression.

Example of tension --> a force present in towing ropes or lifting hoists.
Example of compression --> à forces in the leg of a chair as we sit on it or forces in the support pillars of building.

### MECHANICS OF MATERIAL- CONCEPT OF STRESS

INTRODUCTION
the main study obkective of the mechanics of materials is to provide the future engineer with the means of analyzing and distinguishing various machine and load bearing structure involve the determination of stresses and deformations. Mechanics of materials will deals with the concept of stresses. There are 3 main type of stresses that we will learn:

• normal stresses
• shearing stresses
• bearing stresses

the aim of this subject is to provide foundation knowledge in stresses, strains, and displacements of deform body, produced by the exerted loads.

the basic outcomes of this subject are as follows:

1. define and determine the concept of stress-strain diagram.
3. analyse the transformation of the component of stress and strain.
4. analyse the stresses and strains in prismatic members subjected to bending.
6. analyse the design of vertical prismatic members supporting axial loads.
7. analyse and design of shafts subjected to twisting couples.
8. analyse the stresses and deformations in structures using strain energy.
