Learning outcomes |
Teaching the application of basic principles of mechanics in engineering problems.
At the end of the course the student should be able
* to analise a problem of applied mechanics,
* to choose an appropriate system model,
* to study force system reducing it to an equivalent system of forces,
* to analyze the equilibrium of a solid body in plane and space,
* to study reactions in a structure or a machine,
* to draw diagrams of internal forces in beams,
* to consider changes in movements of machinery,
* to calculate dynamic reactions for a rotating body,
* to apply the principle of virtual work to calculate the active forces and reactions,
* to write the equations of motion of a mechanical system in generalized coordinates.
