hi ive just been given this piece of coursework which is the latest(2008) version and im just wondering if I could get any help on this? thnx! :cheesy grin: The manufacturers of wood floors need to know how much the wood expands and contracts with changes in humidity and temperature. One way of detecting expansion or contraction is to use a strain gauge. You are required to design a laboratory experiment to investigate how the resistance of a strain gauge attached to a piece of wood varies with the temperature of the wood. You should draw a diagram of the apparatus, and in your account you should pay particular attention to: (a) the procedure to be followed (b) how the strain gauge would be attached to the wood (c) the range and precision of any instruments that would be used (d) the factors that would need to be controlled to ensure that it is a valid test (e) any safety precautions you would take when carrying out the experiment (f) particular features of the design that would ensure the accuracy and reliability of your results any help on this would be great!
