1. The problem statement, all variables and given/known data Ok, so in a lab I was preforming Izod impact tests on notched polymer specimens. To complete my calculations I need to determine the correct cross-sectional area to use (Which is baffling me as the simple things usually do) The sample was loaded with the notch facing the direction of the pendulum. 2. Relevant equations Width 12.97mm Thickness 5.87mm Length 62.61mm And the Notch is 2mm deep at an angle of 45° 3. The attempt at a solution So I haven't got far with my attempts at the problem because I'm liteally clueless at where to begin and how the notch will effect the cross sectional area. Any help or tips will be greatly appreciated!
