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.
