Identifying the smallest loadPU for a prescribed loading defines MP (or vice versa). This process requires the student toanalyze the beam visually and locate possible collapse modes. There is no need to determinereaction forces.An illustration of elastic and plastic methods is provided by the beam below having equalspacing L between pin supports at A, B, … E and fixed support at F. Identical loads P areapplied at mid points of panels AB, BC, and DE. The objective is to determine Mmax . .Elastic analysis uses the deflection equation, y’’ = M(x

of interfaces is a matter ofconcern for software developers, and might be a barrier in solid modeling education and inengineering practice7. This is because it is believed that the layout of GUI elements influencesthe way users can interpret these elements8. While the user’s correct mental model of theinterface can help with their productivity, a false image of the interface might mislead them andlimit their ability to work with the software effectively9. For example, a recent experimentalstudy showed that, if an unknown icon A in software 1 looked like a well-known icon B insoftware 2, the users supposed that the icon A represented the same function as the icon B, evenif both pieces of software were quite different10.

Although the pendulum exhibits periodic motion, however, as already shown in Fig. 2(a), it is not necessarily harmonic as the linear model predicts.2) For E > 1 , the pendulum motion is characterized by open trajectories. The motion is rotary with continually increasing amplitude as shown in Fig. 2(b).3) As E approaches to 0, the pendulum motion becomes harmonic, increasing the validity of the linear analysis.
