STRESS MEASUREMENT ON TRAIN WHEELS
Abstract
Ultrasonic velocity is a type of mechanical pulse or longitudinal waves
which bring about a state of alternative transmit and receive of the
textures in the material. The velocity of sound is constant for any given
medium although it changes from medium to medium. The pulses of sound can
be described as seperatilly events within the material following a waveform.
Bigger the density, the interior the velocity. The higher the elasticity, the higher
the velocity.
