4 Point Bending Tests are used to test samples of a material. 13 1 13- P12 Write a MATLAB function named bending to calculate information about the material for each The function will have three inputs and two return values The first input will be the applied load P - The second input will be the support span L The third input will be the measured elastic deflection d The first return value of the function should be E the elastic modulus . The second return value should be o the maximum stress To determine the first return value, use this equation to determine the elastic modulus E - 10 PI3 0.0013 d. To determine the second return value, use this equation to determine the maximum stress 50 PL 0= 0012 Notes: Example Test Case: [modulus, stress] =bending(5, 0.18, 0.0015) results in modulus=194.4 x 10 (194.4GPa) and stress = 45 x 106 (45MPa) DO NOT include test cases
