NB! This course will take place in autumn semester 2025/2026 which starts on 1st of September and ends on 25th of January (you can find that information under Start date section). TalTech's timetables for Autumn semester 2025 will be published at the end of June via tunniplaan.taltech.ee. Switch the page to English and use "Search" and "Open detailed search" to find your course. NB! Some courses are taught by several lecturers during the same semester. Make sure that the course name and lecturer/teacher infromation of your course match with the information given in the Course Catalogue.

Having successfully passed the course, the student:

• have the general knowledge about the theoretical basics of the problems of Statics, Kinematics and Dynamics;
• is able to compile basic calculation schemes in order to solve the general problems of Statics, Kinematics and Dynamics of rigid bodies;
• is able to solve the basic equilibrium and motion equations analytically;
• is able to analyse the correspondence of the results obtained to reality;
• is able to apply modern computer software to solve simpler problems of statics, kinematics and dynamics;
• is able to interpret the results in terms of the original statement of the problem.

Final assessment can consist of one test/assignment or several smaller assignments completed during the whole course. After declaring a course the student can re-sit the exam/assessment once. Assessment can be graded or non-graded. For specific information about the assessment process please get in touch with the contact person of this course. For specific information about grade transfer please contact your home university
