ME586 – Experimental Mechanics and Applications Due by 11:59 PM, August 5. Name: Mohammed Al Garzae Describe a procedure for determining if bubbles exist under s a strain gage. 2. A video clip on YouTube shows that a group of students attached strain gages as shown in the figure. Is this the best way to run the experiment? Please comment on this. 3. Spin coating is a typical procedure used to deposit uniform thin films to flat substrates. Please describe an optical method that can accurately measure the thickness (a few microns) uniformity of the photoresists (transparent) coated on a silicon wafer. 4. What are the differences between accuracy, precision, resolution, and sensitivity? 5. What is the typical measurement sensitivity of the following technique? (a) Twyman- Green Interferometry, (b) moiré interferometry. 6. Explain the basic principles of the photoelasticity method and the thermoelastic stress analysis method. 7. Describe the advantages and disadvantages of the DIC (digital image correlation) technique. 8. Describe the principle of micro-CT (Computed Tomography) and how it can be used in mechanics measurement. 9. Describe a technique that is capable of detecting low-frequency vibrations generated by water leakage from underground pipes and transmitted to above the ground.
