Longitudinal Velocity of Free End is the velocity of the free end of a vibrating system, affected by the inertia of constraints in longitudinal and transverse vibrations. And is denoted by Vlongitudinal. Longitudinal Velocity of Free End is usually measured using the Meter per Second for Speed. Note that the value of Longitudinal Velocity of Free End is always positive. Typically, the value of Longitudinal Velocity of Free End is greater than 0.
