We have addressed numerous information and tackled numerous assignments and tasks has the course progressed resulting a situation whereby the students think and operate like experienced engineers. The progress in classroom and the inspiration received from other quarters increased our confidence in tackling the problems and we understood that there are many solutions to a single problem and it is appropriate to choose the suitable. Therefore, in the current problem, the students are expected to obtain 8 outcomes by solving the problems. The Outcomes First Outcome “Apply fundamental knowledge of mathematics and science to solving engineering problems” In solving numerous issues in daily life, we normally utilise our background and with the knowledge obtained through reading and experience, we can solve an issue easily. Most of these problems utilise science and mathematics in solving problems associated with sciences such as physics and mathematics. Therefore, background information doubled up with learning plays an important role in identifying and solving engineering based problem. An example is the 3rd activity titled “energy”. I realised there are numerous ways in which energy can be converted from one form to another provided we understand how the system operates. For example, it is easy to convert an engine that utilises fuel to an engine that utilises natural based on the understanding energy is transferable. I utilised information from previous lectures such as the “energy background knowledge” in understanding factors such as thermodynamics and helped me to understand that work and heat is directly associated. This can be understood by studying the following equation: H = W in joules unit Moreover, the following equations are important and I can easily different and understand its applications. These formulas are: 1. ΔEx = Q + W 2. ΔUx = ΔQ- ΔW E stands for work done on the system by the surroundings U refers to work done by the system on the surroundings Another important formula is  which I utilised to calculate the engine cylinder volume with the aim of obtaining the engine compression ration. The diagram below illustrates the components that make up the equation. In addition, understanding graphs and be able to draw the graphs has helped me to draw the graphs indicating the inlets and outlets temperature for a radiator; engine cooling system. The drawn graph was a proportional of runs R against temperature T. This also contributed in drawing of the thermocouples truth tests. Another important activity and has helped me to understand engineering is the 4th activity titled “surveying”. The importance of surveying brings into consideration trigonometry that brings the understanding and knowledge of estimating heights without actually been at the given location or near the tower. (1) – The Sin Rule – The sin rule is based on the following equation: Whereby, the initials a, b, c are indicated by the following sketch triangle (2) – The Law of Target – Another important rule is that of target indicated by the following equation: We went to a field trip whereby we utilised a theodolite to determine different types of angles. We employed the equation from number 1 (the Sin rule) to determine the distance from the theodolite to the tower from two stations: station 1 and station 2. The second formula was utilised to determine the height of the tower. The formula assumed a drawing on D which is a vertical triangle. In addition, in 1st activity, the “digital” we were asked by our instructor to develop a home alarm system and employed subtraction, addition, multiplication and division and the Boolean algebra in formulating and determining truth outputs of our truth table. This information is further elaborate on the Digital’s report. In the second activity, we learned about “hydraulic” and we were able to understanding the changing rate of the water flood verses pressure. Second Outcome The second outcome is based on “Apply systematic approaches to solving engineering problems” This is based on the philosophical saying that a journey of a thousands mile starts with a mile. In order to design, develop and solve any problem in different aspects of life, it is imperative to follow a standard procedure to ensure a quality work is achieved. In engineering related problems, there is a fixed term that is used in solving any problem and it is also tailored through its flexibility to fit each problem solution. To achieve this requirement, there are some steps in which are followed. These steps are: 1. Gathering and planning – this section is for the students to know each other and also to provide details that enables them to contact each other. Moreover, this step requires these teammates to choose the meeting date. 2. Analysis of the problem – this is the time whereby the students analyses the problem and determines the approach in which the best solution can be obtained. 3. Research – this is the step in which the students could collect information that would assist in solving the problem. 4. Meeting – this is the stage in which information collected is analysed and discussed. The students will taken brainstorm and resulting in obtaining the appropriate solution to the problem. 5. Utilisation of the solution – the students utilised the appropriate solution in ensuring the problem is solved Application of the above steps in solving a specific problem The above steps were utilised in solving the 3rd activity under “energy”. After understanding the problem of the engine the students worked to find the most appropriate solution. The problem in which the students were to solve is conversion of engine compression ratio to 12:1 The teammates came together and did some research on the subject The team proposed their solutions during the meeting and they decided the best solution. The three proposed solutions are: 1st solution – leaving the compression ratio the same 2nd solution – reduction of cylinder head thickness 3rd solution – reduction of head gasket thickness Two engines were analysed which are the motor vehicle engine and a stationary engine. The compression of the motor vehicle engine was 6:1 and this was easily to convert to be utilised by a natural gas engine. The stationary engine had a compression ratio of 6:1. The team decided that it is important to increase the ratio to between 10:1 and 12:1. The ration was obtained by reduction of the cylinder head thickness or reduction of the head gasket thickness. Refer to the Energy report for further analysis The requirements for the 4th activity, “surveying” is to calculate the height of the tower utilising trigonometry rules and theodolite. The team researched on theodolite through reviewing information about it and also application of the technology. The team members followed the above steps in accomplishing this requirement. Regarding the 1st activity, “digital”, the team members researched on Boolean algebra. The team members also researched and discussed on the topic problem which is “how to build and develop car alarm system”. The team analysed and examined one of the cars with the aim of understanding alarm system and how the alarm system works. The team members discovered that there are two outcomes for the alarm system to ensure the entire process is effective. The team employed the help of the teacher while building the truth table. Third Outcome “Find, organize and apply information related to engineering problems” For these numerous problems, I did my own research regarding the course plus the problem and through the process, I developed my knowledge regarding the problem and I choose the most appropriate solution for the problem. Most of the information, which is relevant and applicable, was available under the folder ‘Web-CT’. In addition, I researched on other sources in collecting the appropriate information. I utilised The Harvard referencing style in acknowledging external information plus formatting of the report Fourth Outcome “Identify and respond to broad sustainability issues in finding solutions to engineering problems” The method in which the problem was solved can be applicable to many similar projects. For example, solving the problems in this approach is similar to solving engineering and the community (ENF 1103) course. In helping the environment, we partnered with Engineers Without Borders with the aim of developing projects that can improve community and elevate problems faced by people in East Timor. We were then divided into different teams in which each team was supposed to identify a problem and develop a solution that addresses the problem. We (the team members) choose to deal with water supply and sanitation part. The team examined the requirements and needs of Codo and then the team developed and presented three solutions. From the three solutions, the team members decided on solar power as the most efficient solution. The detail of the research and the solution to the problem is titled “Water Supply and Sanitation System in Codo, East Timor”. Fifth Outcome “Communicate effectively with others orally, in writing, and by means of basic engineering drawings” Communication is a major issue because I am an international student and also my team mates. English is not my first language and thus I cannot communicate effectively in this subject. I was able to communicate with my teammates through talking rather than texting or emailing them. During my time in the course, I was asked to write two long reports. Since my spelling and grammar was not effective, I usually ask native English speakers and Native Australians to proof read the report with the aim of helping in editing. Nevertheless, I am working hard to improve my vocabulary. Moreover, I utilise spelling correction software in checking my completed reports. In addition, I usually search for synonyms on dictionary.com during working on my reports. Sixth Outcome “Work individually and collaboratively in a team environment” In ensuring that effective work is achieved, it is important to work in a team and also it is important sometimes to work individually. I have been looking for appropriate information in which I later share with my friends through group discussion. I usually set my timetable and I utilise my phone as a note book as indicated in the following screen shots During the discussions and frequent meetings, I make notes in ensuring information is stored. These are some of the examples of notes that I have made. I sometimes communicate with my teammates by emails and phone. The following are some of the examples of my communication with friends. In writing the report, we usually divide the work equally. Each member is responsible for a specific part of the report and the member is supposed to fulfil the requirement of their section. As an example, my work was discussion in the surveying activity In addition, on the report on Engineers without Borders, my part was “Introduction and background information of Codo, East Timor” Eight Outcome “Maintain a personal reflective journal on their learning” The information regarding this section is available at the reflected journals section Peer Assessment During our study in the course, we were responsible in assessing our peers. Some of the tasks brought into consideration during assessing include performing oral presentation or watching the students to perform experiments and also recording the data. This assessment was important because we were able to give constructive feedback regarding accomplishment of our peers and also helping in fulfilling the different obligations. This is based on the fact that different peers have different strengths and weaknesses and it is important to understand such factors to ensure effective advice is offered. Conclusion The subject has played an important role in shaping my beliefs and benefiting through analysing, team work, and problem solving and searching. I improved my knowledge on engineering and also have improved my problem solving skills in helping in fulfilling the engineering obligations. Through the outcomes of the process, the gains achieved would play an important role in my future studies and also my future life. The subject enabled me to do team work which contributed to building of confidence and hence I better understood the engineering subject. Read More
