My parents just got a call from the headteacher saying that my Computer Science coursework is under investigation by the exam board and I have to meet with my exams officer and head of IT to form a response to a letter from the exam board.
Learn about elasticity and how to determine the force exerted by a spring. What is a spring? A spring is an object that can be deformed by a force and then return to its original shape after the force is removed. Springs come in a huge variety of different forms, but the simple metal coil spring is probably the most familiar.
Springs are an essential part of almost all moderately complex mechanical devices; from ball-point pens to racing car engines.
There is nothing particularly magical about the shape of a coil spring that makes it behave like a spring. The 'springiness', or more correctly, the elasticity is a fundamental property of the wire that the spring is made from. Winding the wire into a spring just allows us to exploit the properties of a long piece of wire in a small space.
This is much more convenient for building mechanical devices. In addition, the elastic properties of metals depend strongly on their grain microstructure.
If a metal wire was formed from a straight section into a coil then it is likely that it would need to be re-annealed to restore its original elastic properties. What happens when a material is deformed?
When a force is placed on a material, the material stretches or compresses in response to the force. We are all familiar with materials like rubber which stretch very easily.iridis-photo-restoration.com The International Commission for Uniform Methods of Sugar Analysis Ltd.
(ICUMSA) is a world-wide body which brings. Robert Hooke dicovered cells and the law of elasticity, or "Hookes law" its still used today.
Year Curriculum Content – Year English. Students in Year 10 are following the Cambridge IGCSE syllabus for English Language. There are three components to the course: a reading examination worth 40%, a coursework unit worth 40% and a 20% speaking and listening examination.

Laws of Motion and Thermodynamics Essay. When watching tennis match or any other sport who of thought science played a big part?Laws of Motion and Thermodynamics Essay. Hooke's Law is a linear function, the spring constant of the series spring set should be exactly half that of a single spring, whereas the In this physics coursework, I'm here to investigate the oscillations of a mass of a spring.
In this investigation, the oscillation means the wave moving with periodic regularity.
