ME 352 focuses on dynamic energetic systems in which change occurs when energy flows from one element to another. Dynamic models are used by mechanical engineers to predicts displacements, velocities, accelerations,forces, and torques needed for design calculations. An example of an energetic system, a rack and pinion used in automobile steering mechanisms, is shown in the figure below . Dynamic models can include different types of physical systems. A dynamic model be used for designing hydraulic powered machinary, such as a backhoe used in construction, would include both mechanical and fluid elements.
Vibrations are a dynamic response of mechanical systems.
A beat is often heard on airplanes because the engines run at slightly different speeds. Last updated January 23, 1999.
