6.6 Oscillators in general

Although this section has dealt only with mass-spring systems, the analysis can be extended to any system where there is an oscillating driving force acting on a mass which is located by a restoring force. In fact, the analysis is even more general than this and can be applied to electronic networks where voltages and currents oscillate in much the same way as the mass on the spring.

6.1 Why is resonance important?

This section aims to take you through some general ideas about vibrations, which will help you understand the principles behind the resonant behaviour of the AFM probe tip. Vibrations and oscillations crop up in many contexts. They can be modelled mathematically and form a general topic in mathematics about vibrations and oscillations in which the appropriate balances between forces and accelerations are formulated into differential equations.

5.1.2 Dipole-dipole forces

In the case of dipole-dipole interactions, the molecules that bond together have a fixed asymmetry in their charge distributions (as is the case in Figure 22); if their orientations are favourable the two will bond together. All molecules produce London forces. The dipole-dipole interactions are in addition to t

6 Radiation

All the primary vibrators we discussed in the previous section can to some extent communicate vibrations to the surrounding air and hence radiate sound. However, some radiate sound better than others. Air columns, for example, radiate sound quite well. Even though only around 1% of the energy possessed by a vibrating air column is radiated away, this is enough to produce a clearly audible note.

Similarly, circular membranes and circular plates are also good sound radiators. They have a

5.2 Owen in London 1812–14

Owen's visits to London, where he worked on the essays, coincided with the vital closing years of the Napoleonic Wars. He arrived in the metropolis to find it seething with news of momentous events on the Continent, especially Wellington's victories in the Peninsula and Napoleon's retreat from Moscow, of the course of the war in the United States, and, closer to home, of a series of political crises made more acute by the growing unrest in the country. While the international situation remain

4.1 Facial expression

Facial expression was considered the most crucial element to success in painted portraiture. It was the vehicle through which intangible qualities of mind and soul were conveyed. In painting the idea was to achieve the ideal expression, a synthesis of character and the spiritual essence of being. Although cameras could portray any number of expressions with relative ease – an advantage of the machine over manual practice – early portrait photographers continued to believe in the ideal exp

4.1.4 Summary

  • Identity is based on being the same as some people and different from others.

  • Identities are constructed in relation to place.

  • Difference is unequally weighted and can create categories of outsiders.

  • Individuals and groups have to negotiate both the uncertainties of social change and the constraints of inequality.

3.4 Audio activity

Using audio is a very idiosyncratic practice amongst Open University students. Some listen to them in the car, others on a personal stereo on the train, some while washing up, others at their desk. Flexibility of use is certainly one of their virtues. However you use them, some of the following may be useful guidelines.

  • Read the notes for the activity before you listen. At the very least try and fix in your head or note down the main purpose of the a
