AUTO CAD Assignment

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.

STRESS AND STRAIN –LOADS

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.



LOADS
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.

TYPES OF LOADINGS

TYPES OF LOADING	EXAMPLES
Static or dead loads	Non fluctuating stationary loads. (generally caused by self-weight of structures)
Live loads	Moving loads, for example vehicular loads on bridges.
Impact or shock loads	Loads caused by sudden blows.
Fatigue, fluctuating or alternating loads	Loads where magnitude and direction change with time.

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.
2. analyse the deformation of a structural member under axial loading.
3. analyse the transformation of the component of stress and strain.
4. analyse the stresses and strains in prismatic members subjected to bending.
5. analyse the design of beams under traverse loading.
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.
   
   
   

OVERVIEW FOR VNM OF UNISEL'S ENGINEERING FACULTY

FACULTY VISION
“To Be the Forefront Industry-Oriented Engineering Faculty”

FACULTY MISSION
“Faculty of Engineering is committed in providing comprehensive and industry related expertise and stimulating knowledge-culture atmosphere”

PHILOSOPHY
“Honest and Professional in the Quest for Continuous Improvement and Knowledge Advancement with Responsibilities to the Creator and Stakeholders”

ESQ TRAINING PROGRAMME

MY FIRST EXPERIENCE IN JOINING THE FACULTY PROGRAMME WAS ESQ TRAINING. IM VERY HAPPY WITH THE ACTIVITIES AND MOTIVATIONAL TALK THAT WAS HELD FROM 9.00AM TO 5:00PM. I WANT TO THANK ALL OF LECTURERS WHO SPENT THEIR TIME TO GIVE US GUIDANCE AND TRYING TO SOLVE OUR PROBLEM IN A PROPER WAY. IN ADDITION, IT WAS VERY INTERESTING TO MEET LOTS OF FRIEND FROM DIFFERENT BACKGROUND. HOPEFULLY, THEY WILL IMPROVE THEMSELVES FROM TIME TO TIME SO THAT THEY WILL GRADUATE FROM UNISEL WITH A FLYING COLOURS RESULT AND ACHIVE THEIR FUTURE GOALS.

STRENGTH OF MATERIALS - ELASTICITY

STRENGTH OF MATERIALS

MY FIRST LECTURER IN THE STRENGTH OF STRUCTURE CLASS IS MR MOKHTAZUL HAIZAD. HE WILL BE TEACHING ME DURING THIS SEMESTER. I WILL SHARE MY NOTE AND LATEST ISSUE WHICH DISSCUSSED IN CLASS WITH ALL OF YOU. HOPEFULLY IT WILL BE USEFULL FOR YOUR REFERENCES. THANK YOU.

ADVANCE ENGINEERING MATEMATICS

MY FIRST LECTURE WAS VERY INTERESTING. I HAVE A VERY WELL PREPARED LECTURER FOR MY CLASS NAMED DR. SAIMAN. WE WILL BE FOCUSSING ON THE INTEGRATION PART. HOPEFULLY I CAN SHARE MY LESSON DURING THE CLASS WITH ALL OF YOU ALONG THIS SEMESTER. MY BLOG WILL BE COMING VERY SOON.... THANKS FOR VISITING MY BLOG:>
