In solid mechanics, analyzing three-dimensional stress problems can quickly become complicated and time-consuming. However, some simplifications can make these problems more manageable. One of the ...

Nat 5 Maths - Working with three-dimensional coordinates Work with 3D vectors, using the xyz plane as part of National 5 Maths.

However, in two- and three-dimensional cutting stock problems the heuristics are not so good which necessitates the research of effective exact methods. In this paper we present an exact solution ...
