Course detail

Dynamics

FSI-5DTAcad. year: 2012/2013

The course “Dynamics” makes the students acquaint with basic axioms, laws and principles of theoretical and applied mechanics. Gradually students go over the following areas of dynamics: basic axioms, general dynamics of a particle, dynamics of a system of particles, dynamics of rigid bodies, moments and products of inertia of rigid bodies, dynamics of a system of rigid bodies (planar models), fundamentals of analytical dynamics (Lagrange’s Equations), linear vibration of systems (free, damped and forced vibrations with one and n degrees of freedom).
In this subject is realized practice, where the students will provided measurement if variable nechanical values (displacement, velocity or acceleration) on real dynamic systems, such as: automatic cafee-machines, electronic sewing machine etc.

Learning outcomes of the course unit

Dynamics deals with kinetics, i.e. with the relationship between motions and forces. Students will be able to: Construct and analyze free body diagrams (FBD) and write equations of motion of this body. Solve problems of systems of rigid bodies altogether using work and energy and Lagrange’s equations. Analyze dynamic systems and recommend changes, as well as to analyze the effects of those changes. Solve simple linear vibration systems.

Prerequisites

Solving simultaneous linear a quadratic equations. Trigonometry and analytic geometry. Differentiation and integration of one variable. Vector algebra. Vector representation of forces and moments. Free body diagrams. Solving homogeneous 2nd order differential equations, and the general 2nd order linear differential equation.

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

The course-unit credit is granted under the condition of active participation in seminars and passing the seminar tests of basic knowledge (at least 15 ECTS points out of 30 must be gained). The points gained in seminar tests are included in the final course evaluation.

Final examination: Written part of the examination plays a decisive role, where the maximum of 70 ECTS points can be reached. Solution of several computational problems is demanded. The problems come from typical profile areas of given subject and can be supplied by a theoretical question, proof, etc. The lecturer will specify exact demands like the number and types problems during the semester preceding the examination.

Final evaluation of the course is obtained as the sum of ECTS points gained in seminars and at the examination. To pass the course, at least 51 points must be reached.

Aims

The objective of the course “Dynamics” is to familiarize students with basic principles of mechanics as well as methods applied for dynamic solving of mechanical systems. The emphasis is on understanding the physical principles governing motion of rigid bodies and applying them to solve simple technical problems in practice.

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.
