Question 3:
With an appropriate sketch critically discuss the working of the Huggan Berger extensometer.
Question 4:
In brief illustrate the advantages and disadvantages of the mechanical strain gauges.
Question 5:
Develop expression for cross-sensitivity (transverse sensitivity) factor of the electrical resistance strain gauge with semi-circular bends.
Question 6:
Develop expressions for fringe order in a stressed model kept in bright field combination of a circular polariscope.
Question 7:
Illustrate out clearly the shear difference technique of separating the principal stresses.
Question 8:
Clearly discuss any two of one destructive testing method.
Question 9:
Clearly illustrate out the crack detection and crack multiplication methods in brittle lacquer coats.
