1. Forces: decomposition and sum of forces using both an analytical approach (vector algebra) and a graphical approach (e.g. force polygon); moment of a force; Varignon's principle; couple; equivalent force systems; force and moment equilibrium. (Chapter 1, 2, 3.1-3.3, 4.1 - 4.9)

2. Mechanical systems: force and moment equilibrium of 3-dimensional mechanical systems; schematisation of engineering problems; loads; supports and connections (e.g. hinges); degree of freedom of supports and connections; reaction forces and moments; statical and kinematical nature of a mechanical system (determinate or indeterminate). Chapter 3.4, 4, 5.

4. centre of mass; area moments of inertia, parallel axis-theorem, aera moments of inertia for thin-walled structures, mass moment of inertia. Chapter 9.1- 9.3, 9.5, 10.1 & 10.5, 10.9

5. Internal forces: evaluation of normal force, shear force, bending moment and torsional moment in a bar; notation and sign conventions; differential equations; deformation signs; relations between normal force, shear force and bending moment diagrams. Chapter 7.1 - 7.3 + hand-outs.

6. Frames and machines: analysis of the equilibrium of interconnected bodies; normal force, shear force and bending moment diagrams of frames; evaluation of reaction forces and moments. Chapter 6.6, 7.1 & 7.3.

Course Contents
Statics deals with the principles of equilibrium. In this course the principles of forces and moments will be explained as well as principle of equilibrium of forces and moments. This also includes the equilibrium of 2D and 3D structures and trusses. Furthermore the principle of internal forces and moments is addressed as well as the use of the principle of virtual work to calculate both external and internal loads. Finally, the concepts of centre of gravity, centroids and moments of inertia are discussed.
Study Goals
At the end of this course, the student will be able to to solve basic problems dealing with statics. They will be able to:
- Define the basic terms in statics such as force, moment, body using the appropriate units and notations
- Use Newton's 1st law to determine the reactions on 2D and 3D bodies and particles in equilibrium
- Calculate the centroids and mass and area moments of inertia of elementary shapes (including thin-walled structures)
- Analyse whether a structure is kinematically and statically determinate and calculate the normal forces in a truss
- Be able to calculate and construct diagrams of the distribution of internal normal forces, shear forces, bending moments and torsion moments as a result of external loading including distributed loads.
- Be able to use the principle of virtual work to derive internal and external forces and moments of structures and systems.

Lectures and instructions
Literature and Study Materials
Engineering Mechanics - Statics by R.C. Hibbeler, 12th edition in SI units, Pearson Prentice Hall incl. Mastering Engineering access code. ISBN 9789810683993.

Please note:
Use this ISBN number only when ordering. As otherwise your access code for Mastering Engineering (the mandatory computer support software) will not be included.

Secondhand books cannot be used for this course as they do not come with an access code which will then have to be purchased seperately and will end up being more expensive overall!

Senior students with no access code will be informed via Blackboard on how to obtain an access code. This also applies to students who accidentally bought the book new without access code providing they have a proof of purchase (receipt).
Written exam (open questions)
Permitted Materials during Tests
Prerequisites for taking part in the exam (regular session or resit):

A. Students are allowed to take an examination only after successfully completing the Computer assignments. To complete the Computer assignments, a student must obtain at least 30% of the total number of points for each successive group of four blocks (i.e., block 1 to 4, block 2 to 5, etc). In addition, a student must score at least 40% of the total points, averaged over all blocks. The final scores are determined on the last Friday afternoon (at 23.59) before the examination period.
Each block will be closed five working days after the corresponding lecture week at 23.59(i.e. block 1 will be closed on Friday afternoon of the second lecture week, etc.). After the regular examination, all blocks will be reopened until Friday 23.59h prior to the resit exam period.

B. The results of the computer test are valid during one full academic year only. If the requirement for participation to a regular examination is met, the student is also allowed to take part in the resit examination during the same academic year. The results of the computer tests are no longer valid after the end of the academic year. Consequently, students must complete the Computer test requirement once again in order to be allowed to take part in examinations in the subsequent academic year.
Students attend the active lecture, in which new topics are introduced and examples are completed with student input to provide insight.

After the active lecture, students undertake self-study either together or alone on 10 computer-based assignments that must be completed each week.

The assignments form an entry requirement for the exam.

Once a week they are expected to attend an instruction in which they practice problems from the book under supervision of a teaching-assistant. This is also an opportunity for students to ask for assistance with the computer assignments.
