Learning outcomes

The course focuses on the theory and solution of technical problems from the field of mechanics of rigid bodies. The students learn to analyze simple mechanical systems, draw the free-body diagram and to assemble and solve the equilibrium equations or equations of motion. The course is divided into four section - statics, kinematics and dynamics of rigid bodies, and fundamentals of engineering fluid mechanics. The presentation of the theory is complemented by solved example problems from engineering practice.
Students will acquire the basic knowledge of the technical mechanics of the rigid body, and elementary concepts of engineering fluid mechanics. Special focus is given to free body diagrams and their application in problems of statics and dynamics. Concerning statics, the student is able to write down the equations of equilibrium of bodies and systems in statically definite cases. Concerning kinematics, the student is able to transform different descriptions of motion. Concerning dynamics, the student is able to write down equations of motion for basic cases of particle and rigid body motion. In the fluid dynamics, the student understands flow in pipes, drag and lift on immersed bodies.
