An immediate consequence of the viscoelasticity of polymers is that their deformations under stress are time dependent. If the imposed mechanical stress is held constant then the resultant strain will increase with time, i.e. the polymer creeps. If a constant deformation is imposed then the induced stress will relax with time (stress relaxation). Author(s): The Open University

â€˜The whole is more than the sum of its partsâ€™ is a good place to start thinking about systems. A car is more than its individual components. We can think of a football team as being more than a collection of individual players or a family being more than a group of people who share the same name.

Each of these examples â€“ the car, the football team and the family â€“ can be seen as systems. Individual parts of a system are connected together in some way for a purpose.

You may have met the term bit, perhaps in connection with computers. The term 'bit' is also important in communication systems. It is an abbreviation for 'binary digit'. A binary digit can have just one of two values: it can be either 1 or 0. Pulses can be represented by 1s and 0s, that is, as bits, and so it is convenient to think of streams of 1s and 0s being conveyed along the communications link.

The rate at which the 1s and 0s are conveyed is known as the data rate or

A focus group is simply a group of people gathered together to discuss a particular issue. They have been used in all kinds of social and market research, including political policy making. In market research for product design, a focus group might be a group of purchasers of a particular product brought together to discuss their feelings and attitudes towards the product and rival products; or perhaps their general likes and dislikes about those types of products. The intention of the market
