ci3.1 BLOCK DIAGRAM Fig 3.1 block diagram of the vibration measurement system The above figure shows the block diagram of the vibration measurement system. The different blocks of the block diagram are the sensor which is used to measure the vibrations. The sensor we are using in this project is MMA8451Q accelerometer, which is able to measure the vibrations. The vibration data need to be measured from the acceleration data of the accelerometer by setting different thresholds. Then the data from

P7 perform and record the results of one destructive test and one non-destructive test using metal and one non-metallic material. The two tests that we conducted were a non-destructive tap test on a piece of an aircraft floor panel, and a destructive tensile test on a tensiometer. The non-destructive test is designed to identify internal or external structural damage of a composite. The material we are testing is an aircraft floor panel that is made of two sheets of glass or carbon fibre reinforced
