Course detail

Theoretical Mechanics

FSI-STMAcad. year: 2010/2011

Kinematic relations and quantities (position, velocity, acceleration) related to the motion of a point, a rigid body and an assembly of rigid bodies are discussed. Also dealt with is the kinematic solution of rectilinear motion, rotary motion, spherical motion and general motion. In the case of relative motion the corresponding kinematic quantities are given. Subsequently, basic terms of dynamics of a particle, mass-geometric characteristics of rigid bodies, dynamics of rigid body/assembly of rigid bodies are presented in terms of vectorial dynamics. The foundations of analytical dynamics are then explained. In the end the theory of vibration of mechanical systems with n degrees of freedom together with the foundations of gyratory vibration of shafts are delivered.

Learning outcomes of the course unit

Students will master basic methodological and logical approaches to the dynamic solution of mechanical systems. The matrix notation is used and therefore the students will be able to solve dynamic problems using computers.

Prerequisites

In the field of mechanics: Vectorial representation of forces and moments. Free body diagrams. In the field of mathematics: Trigonometry and analytic geometry. Vector algebra. Solution to the system of linear and quadratic equations. Differential and integral calculus of one variable. Solution of ordinary differential equations of 2nd order.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Written test examining the knowledge of basic concepts - examination paper containing 3 examples to be solved - oral discussion over examination papers with an optional additional question.

Aims

The aim of the course “Theoretical Mechanics” is to make students familiar with basic axioms, laws and principles of classical mechanics.

Specification of controlled education, way of implementation and compensation for absences

Attendance is required. One absence can be compensated by attending a seminar with another group in the same week, or by elaboration of substitute tasks. Longer absence is compensated by special tasks according to instructions of the tutor. Course-unit credit is awarded on the following conditions: - active participation in the seminars, - good results in seminar tests of basic knowledge, - solution of additional tasks in case of longer excusable absence. Seminar tutor will specify the form of these conditions in the first week of semester.
