|Term Project -- MEE320
||The term project differs from the homework and
other projects in that it is a group effort and it should be a more comprehensive overview
of the issues involved in material selection. Two project options are available.
Material selection for a bicycle frame or a sea kayak hull. There is not a
correct answer for either of these problems. For a sea kayak a number of options
exist -- in particular wood, wood with a canvas or fabric coating, ultralight technology
or a number of different plastic hull designs. For a road bicycle frame all of the
options available to the material scientist have at least been considered for road bike
frames. This includes metal matrix composite, titanium, steel, aluminum, carbon
fiber reinforced plastic etc. Nearly all of these options have their proponents and
are currently used for road bicycle frames.
||This is not a cost no-object problem.
The objective here is to maintain a competitive cost while creating a boat that will best
serve the customer. The issues associated with durability should be considered as
well as cost of manufacturing. The kayak
will be used for light touring off of the coast of Maine. In particular the Maine
Islands Trails and similar trips will be the target use. The kayak is assumed to be
individually owned by someone who uses the boat extensively. The target price
should be consistent with other products in the category. A few manufacturers are Necky,
Prijon, Wilderness Systems, Perception and Dagger. Some of the wood designs are
available as kits from CLC or Pygmy. For folding boats the standard boat is
||The road bicycle is a highly optimized system
of tubes and mechanical systems. This system of tubes and mechanical components is
primarily tied to an athletic competition rather than transportation. The rules
which govern the design of frames are set by the Union Cycliste Internationale (the UCI) . The rules are also
available and interpreted somewhat at the USA
cycling web site -- the organization which represents ametuer road biking in the US
including the olympic games participation. The rules are quite strict and do not allow
many changes in the physical design of the bicycle. However materials are not
controlled and so minor improvements in the material selection are critical to the
competitive advantages of different bicycle designs.
||This is a small group project. You are
allowed to select your group if you want, otherwise you should ask for assistance in
finding a suitable group. The report should include a through survey of existing
solutions to the problem and the use of all that you know about the design process to
evaluate current designs. The current designs should then be contrasted with what
other options are available and then a materials recommendation should be made for design
of a road bike or a sea kayak.
