Physics practical report 2 Oscillations and frequency of wood and plastic metre rules Abstract An experiment was carried out to show how oscillations occur relating to a wood and plastic metre rule and how frequency can be calculated from the results. This experiment involved the timing of oscillations when oscillating meter rules suspended from a bench, the results found that the wood metre rule has a higher frequency then that of the plastic meter rule due to the stiffness (material) of the wood. Materials * Wood meter rule * Plastic meter rule * Load (two 100g mass) * G- clamp * Stop clock * Elastic band * Pen and paper Method The apparatus were set up as shown above, firstly the two 100g masses where fix firmly to the end of the wood metre rule with the elastic band with their centres of gravity positioned at the 99cm mark. The wood meter rule was then clamped to the edge of the...
