1. The problem statement, all variables and given/known data hi guys I am conducting an experiment for my coursework in physics and i have come across a bit of a problem. i am trying to calculate the youngs modulus of 3 different metals Aluminium steel and brass. To calculate the modulus of the material i am using a chart of Mass k/g against the deflection thus giving me the gradient. i am going wrong somwhere as i am getting a result of double the normal GPa for each item i.e 320Gpa instead of 140. see below data and charts that i have created. 2. Relevant equations S=L3/WT3 which is 1796850000 for all metal strips E=4Sg x gradient of graph 3. The attempt at a solution Here is a printscreen of my results, have i graphed them correctly?
