(ft) vs time (sec)
... The figure shows the dynamic free response (amplitude [ft] versus time [sec]) of a simple mechanical structure. Static load measurements determined the structure stiffness K=1000 lbf/in. From the measurements, determine a) damped period of motion Td (sec) b) damped natural frequency ωd [rad/s], c) U ...

Testing Balanced and Unbalanced Forces 15.2 Directions
... Any push or pull is a force. To describe a force, you must know two things. You must know the size of the force and the direction of the force. Suppose two teams are playing tug of war. Each team is pulling with equal force, but in opposite directions. Neither team can make the other team move. Forc ...

6 Work-Energy
... This graph could represent the potential energy of a mass oscillating on a spring, as the work done on the spring is equal to the potential energy at any point on the graph. That potential energy in turn is converted into kinetic energy as the mass is accelerated by the spring. The total energy of t ...

Hunting oscillation

Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
