Course Contents

• Introduction to Engineering. Principles of vector calculus. Force and moment. Moment of a
force with reference to a point and about an axis. Force couple. Parallel force transfer. Reduction of a
system of forces.
• Composition of concurrent and parallel forces – graphic and analytical calculation of the
resultant. Decomposition of forces into components. Forces in space.
• Calculation of the area of surfaces and determining the center of gravity of simple and complex
surfaces.
• Rigid body equilibrium conditions. Mechanisms, determinate and indeterminate structures,
degrees of freedom, types of supports of structures.
• Free-body diagram. Calculation of support reactions.
• Truss structures. Formation – members. Analytical method of nodes. The method of Ritter
sections.
• Complex trusses. Three-hinge trusses.
• Principle of virtual work. Calculation of node displacements of truss

Educational Goals

Students’ understanding of the effect of forces and moments on the static equilibrium of planar
linear undeformed structures. The development of static sensing on the adequacy of links with the
view to achieve rigid and determinate truss structures. The ability to calculate and evaluate the axial
forces developed in the members of truss structures and the displacements of the nodes.

General Skills

Creating the necessary background to enable a full understanding of the concepts and techniques of
static solution of truss structures and of the calculation of the center of gravity of surfaces.

Teaching Methods

Face to face.

Use of ICT means

Powerpoint presentations, E-learning platform for
educational material.

Teaching Organization

Students Evaluation

1. Assignment of tasks in order to investigate the
understanding of the concepts taught.
2. Final written exam at the end of the semester (in Greek).
3. Each student is given the opportunity to check his
examination paper and have his mistakes analyzed.
