Chapter 11, Problem 7P
The pulse�echo ultrasonic technique can be used to determine the thickness of a part or structure. By accurately measuring the time it takes for a short ultrasonic pulse to travel through the thickness of a material, reflect from the back or inside surface, and return to the transducer, the distance can be calculated by:
Where:
- d is the thickness of the test piece.
- VÂ is the speed of sound in the material being tested.
- t is the measured round�trip time.
What are some alternative means of measuring thickness? Briefly discuss their relative pros and cons. Consider such features as geometric and material constraints and the ability to measure from one side only.

- The 2-mass system shown below depicts a disk which rotates about its center and has rotational moment of inertia Jo and radius r. The angular displacement of the disk is given by 0. The spring with constant k₂ is attached to the disk at a distance from the center. The mass m has linear displacement & and is subject to an external force u. When the system is at equilibrium, the spring forces due to k₁ and k₂ are zero. Neglect gravity and aerodynamic drag in this problem. You may assume the small angle approximation which implies (i) that the springs and dampers remain in their horizontal / vertical configurations and (ii) that the linear displacement d of a point on the edge of the disk can be approximated by d≈re.

In other words, if an input u₁ yields the output y₁, and an input u2 yields the output y2, the system is said to be linear if a com- bination of the inputs u = u₁ + u2 yield the sum of the outputs y = y1 + y2.
