The stress intensity factor K at a crack in a beam exposed to pure beading M is given by: K=Ca where =tb26M.a is the crack leogth, b is the width, t is the thickness, and C is a parameter that depends on the geometry of the specimen and crack. For the case of pure bending, C=tan[cos0.923+0.199(1sin)2]where=a/band=()/2 Write a program in a script file that calculates the stress intensity factor K. The program should read the values of M,b,t, and a from the BendingData . mat file attached to this assignment on Blackboard using the load command. The output should be in the form of a paragraph combining text and numbers, something like: "The stress intensity factor for a beam that is (b) m wide and (t)m thick with an edge crack of (a)m and an applied moment of (M)Nm is (K)." where (K) stands for the calculated value of K, and (b), ( t),(a), and (M) stand for the loaded values of b,t,a, and M, respectively
