2. A plastic material was tested in 4-point flexure, quarter point loading. The support span was 50 mm. The sample dimensions were: • • Length: 60 mm Width=w = b = 12 mm (note that the symbol for width can be either w or b) Height = d = 6 mm Use the information given above and the data given in the Excel Spreadsheet (see Isidore) to answer the following questions. A. Make a graph of Stress (MPa) vs. Strain (%) B. Calculate the flexure strength (units of MPa) - show all work C. Calculate the strain to failure (units of %) -show all work D. Calculate the Modulus (units of MPa) - show all work
