Using the techniques of dimensional analysis, and assuming that experimentation shows the dimensionless number to be 1, derive the following equation: E v = Job card two The results of an ultrasonic test on a steel plate is given below: TR If the steel plate is 36 mm thick, estimate the depth below the surface of the crack. Estimate the time delay between sending out the transmission signal (T) and receiving the reflected si (R) off the defect? In establishing the time delay, apply dimensional analysis techniques to show the t in the formula are homogenous and you should clearly state the formula used. Take Esteel = 200GPa Psteel = 7800 kg/m
