Fyodor the bald is standing on the diving board of a certain swimming pool. Because of his weight, the board bends slightly. Then he tries to experiment with it by bouncing on the end of the board. After a few high bounces, the board breaks! The failure of the board is due to the cracks present on its top. Which of the following statements is the explanation of this failure? See figure 02. * The top fibers of the board are under tension, due to the board material's weak under tensile stress. The top fibers of the board are under compression, due to the board material's weak under compressive stress. O There are imperfections in the weaker portion of the top board. The compression on the bottom fibers are excessive enough to cause excessive tension on the top fibers. Figure 02

Crack Detection

Concrete materials are meant for supporting structures, building foundations and they act as several load-bearing structures. Over time, due to environmental conditions, and based on the constituent materials used, concrete materials are subjected to a great degree of distress. Corrosion of the reinforcement bars due to chemical influences, uneven base, earthquake, drying shrinkages, and alkali-aggregate reactions are some of the reasons for concrete distress.

Fyodor the bald is standing on the diving board of a certain swimming
pool. Because of his weight, the board bends slightly. Then he tries to
experiment with it by bouncing on the end of the board. After a few high
bounces, the board breaks! The failure of the board is due to the cracks
present on its top. Which of the following statements is the explanation of
this failure? See figure 02. *
The top fibers of the board are under tension, due to the board material's weak under
tensile stress.
The top fibers of the board are under compression, due to the board material's weak
under compressive stress.
There are imperfections in the weaker portion of the top board.
The compression on the bottom fibers are excessive enough to cause excessive
tension on the top fibers.
