MAKING SENSE OF DATA FINDING A VALUE FOR THE YOUNG MODULUS OF A FLEXIBLE STRIP OF MATERIAL I have picked the first method out of the three options of experiments to conduct based on the flexion of a cantilever. I now have to decide on a method of collecting and processing the data for the first method, taking care to reach a value for Young modulus with some estimate of accuracy attached to it. Method 1: Wood (metre rule) Diagram Apparatus 1. 2 Measuring rulers (1m each) 2. Drawing Pin 3. 9 Weights (50g each, totalling 450g) 4. Approximately 50cm of string 5. G-Clamp 6. Clamp Stand with clamp 7. Screw gauge with a sensitivity of 0.1mm (Micrometer) 8. Vernier Calipers with a sensitivity of 0.2mm The Micrometer Vernier Calipers - read the sliding scale along the top and bottom Variables The variables that will be kept constant are the length of the overhang of the ruler, the position where the ruler is clamped and the position...
