Various case histories of turbo-machinery problems are discussed in this chapter.

Appendix A: Behavioral Similarities Between a Structure and a Human Body

Disclaimer: Discussions advanced here are the sole opinion of the author. Any exercise or workout-routine must be discussed with the primary care physician before embarking on a program.

The author has done limited research on behavioral similarities of a structure (a simple example is a cantilever beam) and the human body. The fundamental mode of a cantilever beam is known to provide the most energetic and flexible condition among all the modes it excites. Analogous to a cantilever beam, a human body bent in that shape can attain most energy and flexibility. See Fig. 8.34. A few body stretches/workouts are discussed.

Fundamental mode shape of a cantilever beam and the human body bent in a similar shape

Three main working systems of the human body and are responsible for healthy living are:

• (a) Digestive System

• (b) Respiratory System

• (c) Immune System.

The human body bent in the fundamental mode shape of a cantilever beam, illustrated in Fig. 8.34, in general, strengthens the three systems of the human body mentioned above; the benefits are discussed below:

Due to high-energy and flexibility, this posture shown in A1 helps stretching the following body parts/organs

• Organs in the abdominal area that participate in the digestive system are: (a) small and large intestines, (b) pancreas, (c) liver, (d) kidneys, (e) spleen and (f) gallbladder. These organs stretch during the exercise routine shown in Fig. 8.34.

• Toes, legs, and back bone structure

• Muscles in the arm

• Bent upper body helps chest expansion

• This posture supports about a third of the body weight, an optimal measure considered in weight lifting

• These exercise routines strengthen the immune system.

• Holding the breath for an extended period of time and releasing it regulates the respiratory system and blood pressure.

• Digestive system is strengthened and regulated since most organs that are responsible for digestion (such as liver, pancreas, intestines and kidneys etc.) participate in this posture.

• Respiratory system is regulated when breath is held in this posture (about 30 s or more) and released after the completion of each routine [1,2,3].

• Immune system improves when the various muscle groups, bones and other organs in the entire body get work-out [4, 5].

• Muscles at the tonsil area stretch with the head bent backwards in this posture; this could improve tonsil conditions.

• Stomach muscles stretch while holding and releasing the breath.

• These exercises activate enough muscle fibers to directly impact mitochondria or reverse the genetic process of aging.

• By working multiple muscle groups simultaneously, as illustrated in Figs. 8.34 and 8.35, complete activation of mitochondria at a level that can impact gaining processes of multiple muscle groups [6,7,8].

  Similarity between the second mode shape of a cantilever beam and the human body posture

Again, second bending mode shape of a cantilever beam and the equivalent human body postures are compared side-by-side in Fig. 8.35. Benefits discussed above apply here as well.
