idea behind the sonic resonance test method can be explained using the equation by which one can measure the propagating speed of flexural sonic wave through a medium
(1)
where v is the propagating speed of the flexural wave on a string, F is the tension applied to both sides of the string, P is the mass per unit length of the string.
Some methmatical manipulation of Eq (1) yields
Ⅰ. Introduction
As our world is called ‘Knowledge-information society’, human resource becomes a major driver of the national competitiveness. Intelligence is one of the most important factors in deciding excellent human resource. Therefore, a country should focus on improving people’s intellectual ability as one way of securing good resource to enhance its competitiveness. We
1.Introduction
1) Motivation of the study
The heaviest investment in sports team occurs in finding a good player. However, some teams succeed in contracting with players who are devaluated in the market, but some teams fail. Because how well the player plays is not measurable in the first place, many professional leagues make statistics that can support people of interest in this ‘risky’ in
3. Experimental tools
1) Ultrasonic detector
It is widespread use of equipment that used in ultra sonic testing. And it also have lots of control function.
2) probe
A protected face transducer is a single element longitudinal wave contact transducer that can be used with either a delay line, protective membrane, or protective wear cap.
3) couplant A couplantis a material (usually liq
