systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from these equations. When applying the second condition we are free to choose any axis about which to compute torques. It is best to choose an axis that eliminates one or more forces that have lines of force that pass

framework uses concepts developed in IO economics to derive 5 forces that determine the attractiveness of a market. Porter referred to these forces as the microenvironment‚ to contrast it with the more general term macroenvironment. They consist of those forces close to a company that affect its ability to serve its customers and make a profit. A change in any of the forces normally requires a company to re-assess the marketplace. Four forces -- the bargaining power of customers‚ the bargaining power

In most examples of industry lifecycles there are either 4 or 5 phases as shown below: | | Typical 4 Phase Cycle | Typical 5 Phase Cycle | The key difference is often how the early or embryonic phases are broken down. Using the global mobile phone manufacturing industry as an example the process would best break down into 5 phases as set out below: * Embryonic (Product Development) At this point (1960’s through early 1970’s) the
