Objectives

BACKGROUD

Mechanical Engineering is a broad and multidisplinary profession. According to 2004 ASME Vision Paper "To meet the demands of the 'Biotech Century,' mechanical engineering must adopt a synergistic, broad-scope approach in which mechanical engineering methodology is part of multi-discipline industrial and research environments.”

Basic scientific knowledge on materials and chemistry are crucial for that. And environmental concerns too.

SPECIFIC AIMS

To help and promote students' learning about:
- materials used in mechanical engineering: metals, polymers, ceramics and composites;
- relations between properties and chemical composition, chemical bonding, structure, defects, processing and use conditions.
To sensitise students to materials selection and its relation with environmental and industrial problems.
To develop the knowledge on the atomic structure and its interpretation by the Modern Science.
To get consciousness of the limitation of Science and human knowledge.
To acquire the knowledge of the fundamentals of Chemistry necessary to understand mechanical engineering phenomena (in thermodynamics, corrosion chemical reactions, etc).

PREVIOUS KNOWLEDGE

Students are supposed to have previous basic knowledge about the constitution of the atoms, molecules and ions, and also mass relationships in chemical reactions.


PERCENTUAL DISTRIBUTION

85% Scientific component;

15% Technological component.


LEARNING OUTCOMES

At the end of semester the students are supposed to have acquired founded knowledge in science and engineering of materials in order to:
-know the different types of materials used in engineering, their properties and applications;
-understand what are the mechanical, optical, thermal and electrical properties of materials;
-understand and integrate all the factors that determine the great diversity of properties that materials can have (chemical composition, defects, chemical bonding, processing, and so on);
- integrate observations and interpretations made in different historical times by different scientists and their contribution to the knowledge on the matter and light.
-became able to solve simple problems of thermochemistry, chemical kinetics and electrochemistry and associate basic concepts of chemistry to phenomena of our daily life;
-have developed the capacity to do bibliographic research works on materials and their applications using the library, internet, visits to companies or stores;
-have developed their team work, written and oral presentation skills.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Description	Type	Time (hours)	Weight (%)	End date
Attendance (estimated)	Participação presencial	56,00
	Total:	-	0,00

Eligibility for exams

To attain frequency, the student must attend at least 75% of the theoretical-practical and practical classes planned (FEUP rules).

Calculation formula of final grade

Final Grade = 20% of the report (bibliographic research) + 65% of the grade of the final exam+15% chemical experiments reports.

Examinations or Special Assignments

N/A

Special assessment (TE, DA, ...)

The special evaluation students are dismissed from attending classes. If they want to, they can take the distributed evaluation component (reports).Otherwise, their classification will be exclusively the result of the final exam.
FEUP rules.

Classification improvement

To improve the classification, the students must submit themselves to the final exam again. If the students want a distributed classification improvement, they must do the bibliographic research report again The classification of experimental reports can't be improved.

Observations

The final exam will last no more 2 hours, without consultation. Language of instruction: Portuguese.
