Technical Report: Material Selection for Dinner in the Sky System

This technical report details the material selection process for a 'Dinner in the Sky' system, a platform designed to operate at a significant height. The report focuses on selecting a material for the platform (10x3 m) and bridge, considering factors like bending load (up to 2000 kg), deflection limits (50 mm), and transparency. The discussion section evaluates various materials like copper, steel, fiberglass, aluminum, titanium alloy, silicon nitride, oak, carbon fiber, concrete, and polycarbonate, based on their tensile stress, yield stress, flexibility, and density. Calculations for rectangular and circular section beams are performed to assess stress and deflection. The conclusion highlights silicon nitride as the chosen material due to its ability to handle bending loads and provide a suitable structure. The report also emphasizes learning outcomes related to mechanical problem-solving, material characteristics, and references various sources for further information. The report follows a structured approach, presenting the executive summary, discussion, conclusion, and references, which offers a clear understanding of the material selection for the 'Dinner in the Sky' system.

1. Executive summary
This complete report is based on the selection of type of material to develop a system that
is named as dinner in the sky. This dinner in the sky is type place or platform at a high
distance from the ground level. To develop these type of system the engineers needs a
base platform which should have a size of 10 * 3 m and the platform must be able to hold
some bending load up to 2000 kg. There will be a bridge which will be used to support
the platform from any imbalance. The entire system must contain a wire that will be used
to lift up the entire dinner in the sky system structure with the help of a crane. The
developer of this entire idea provides one more thing that can provide high sense of
height to the users or customers and that idea is to make the platform transparent. Hence,
this complete report is based on the selection of material to develop this dinner in the sky
system. There are many terms and conditions to decide about the materials such as
material must be able to handle the bending load, weight and some other factors. The
martial also need to select for bridge also and it must not exceed the deflection from 50
mm when the platform is lifting. Similarly, the bridge also has size of 10*3 m. The
report provides a brief idea about material selection for both bridge and platform as per
the dinner in the sky criteria. There are provided a brief discussion about the material
selection including proper conclusion and references. Thus, this is the complete executive
summary about the report for martial selection.
2. Discussion
This is the second phase of the report which is used to provide a brief description about
the selection of material. This is a discussion phase which is describing details what type
of martial will be better for platform and bridge in the system and why we have chose
any material including quality and other factors about the material. Each material holds
different sets of properties as per their standard. There are mainly used properties for any
material is their tensile stress, yield stress, flexibility or elasticity and density. There are
provided the list of qualities for different types of materials such as copper, steel,
fiberglass, aluminum, titanium alloy, silicon nitride, oak, carbon fiber, concrete, and poly
carbonate. There are required a high rate of capacity of material to handle the bending
load so the elasticity of the material should be high but we need to calculate some more
things about the material use to check that the particular material will suitable fit for the
situation. Then, we will calculate the rectangular section beam, Stress for a circular
section beam, deflection for a rectangular section beam because as per the dinner in the
sky criteria the deflection must not exceed form 50 mm., and deflection for a circular
beam. After a successful evaluation of all these terms and findings we are successfully
able to find an appropriate material for dinner in the sky system which is silicon nitride.
This material will be very suitable for this situation because it has high level of flexibility
to handle the bending load and provide a well developed architecture. Thus, this is the
complete details that are what the reason to choose this material is and how this material

will be helpful for dinner in the sky system. Hence, this is a complete discussion about
the selection of material for system.
3. Conclusion
In conclusion, there is selected one material and that is silicon nitride it is able to provide
10*3 m base for dinner in the sky including the ability to handle bending load of up to
2000 kg. Overall, there are described complete details that what additional factors we
need to calculate to find out an appropriate material which can help the developer to
develop a trusty system. The report has great ability to gives some learning outcomes
such as we are able to learn to deals with the mechanical problem when we need to select
any material as per the mechanics background and we can learn about the materials
characteristics and facts that how a particular material can follow some specific
mechanical requirements such as handling of bending load. There are also described
many other factors which are able to provide some helping information to understand the
complete problem and way of solution. The report has an organized and coherent
structure of ideas which are represented in affluent manner. There are described a good
list of references also in the end of this report from which we have taken help to complete
is task to find a material and we can also take some further detailed information about the
field from these reference. Hence, this is the complete conclusion about this report in
which we have selected a material for an interesting system of dinner in the sky.
