...central hole. Because of symmetry we need only model a quarter of the plate. The full plate is 1.0 m × 0.4 m with a thickness of 0.01 m. The central hole has a diameter of 0.2 m. The plate is made of steel with a Young’s modulus of 2.07×10 11 N/m 2 and a Poisson’s ratio of 0.29. The horizontal tensile loading is in the form of pressure of 1.0 Pa (N/m 2 ), along the...

...central cylinder in Figure 8 allows the model to be animated. Turning the crank causes the (representations of the) planets to follow a path around the (representation of the) Sun at the centre of the model. Usually such an animated model is referred to as a simulation. [Described image] Figure 8 An orrery (a mechanical model of the solar system) As with any model, an...

...and CoPs. This re-engagement with the PFMS framework also illustrates iteration as a central principle of STiP. Systemic practice is characterised by iteration – a form of repetition. Iteration involves taking the output of a process and using it as an input for the same process. Applied to learning about practice, this means that you repeat a process of learning on top of the result of prior learning processes, and this ......
