Demonstrate the typical ultrasonic flaw detector in its reflection modes?
A typical ultrasonic flaw detector into its reflection modes is as demonstrated below:
Assume that d be the distance of flaw by the transducer; and ‘v’ be the velocity of sound into the test specimen as well as t be the time of flight. In that case the total distance travelled by the sound into the specimen
v = (2d)/t or d = (vt)/2
The given diagram shows such echo pattern indicating the presence of a defect.
Draw the graph showing the variation of binding energy per nucleon with mass number. Give the reason for the decline of binding energy per nucleon for nuclei with high mass numbers
What is the principle of generating ultrasonic waves? The general principle comprised in generating ultrasonic waves is to reasons some dense material to vibrate very quickly.
What is Power? Power is how fast work is done or energy is used. Example: Remember that cheeseburger (~1/4 pound) I lifted up one meter to do one joule of work? If you now
