Dynamics and Hydromechanics

First cycle, Bachelor

Through the “Dynamics” component, the students are able to: • Analyze physical problems in the field of dynamics independently, • Develop solution methods and devise solutions. • Reduce technical systems of a mechanical nature to the underlying physical principles. • Apply mathematical methods to solve physical problems. • Independently identify problems in technical systems, develop physical models for solutions and estimate the feasibility of physical processes. • Describe, present and pass on knowledge gained. Through the “Hydromechanics” component, the students are able to: • Describe the essential material properties of liquids. • Determine and calculate the forces acting on geometric surfaces due to hydrostatic pressure. • Calculate the momentum of simple geometric bodies. • Apply and calculate the continuity and energy equations to simple hydraulic systems. • Analyze simple systems of pipe hydraulics and calculate the occurring pressure losses, volume flows and flow velocities. • Apply the impulse and twist laws to simple hydraulic systems and calculate the force effect of flowing fluids. • Apply similarity laws to simple hydraulic systems.
