Vincenzo Cassano, a well-known Italian Mafia aimed to torture his enemy, Jang Han-Seok to death by using the drill bit
attached to a piston as shown in Figure Q2. The piston has a
diameter of 13 cm and length of 30 cm. The drill bit is 10 cm
length, and the system has to be located approximately 5 cm
from Han-Seok to ensure a maximum torture, allowing the bit
to penetrate 5 cm into Han-Seok’s chest.
At atmospheric pressure, 1⁄2 of the cylindrical piston is filled up
with water and being heated continuously in a way that there
will be expansion of the water in the piston and the drill bit will
move slowly, and torture Han-Seok. After several trials,
Vincenzo failed to ensure the drill bit works effectively as the
expansion is not sufficient enough to ensure the drill bit hits
Han-Seok’s chest (and now he laughs evilly because the plan
fails).As an engineer, Vincenzo hires you to ensure the
system works well. Using an appropriate P-v or T-v
diagrams, suggest some improvements that he could
make to ensure that he can still use the system with the
same length of drill bit and piston, yet it works well.
Provide necessary calculations (e. g. using the property
table) to proof the effectiveness of this new design,
compared to the initial design.​
