Stress concentration factor (K) at a given point is the ratio between the stress measured at that point and the stress applied at the boundary (in our case σ0). Determine the stress concentration factor for σyy at the point A with coordinates (a/2, 0). Study the convergence of the results using 6 different meshes and make a plot of the stress concentration factor as a function of h/s, where h is the size of the smallest element. Comment on how the size of elements on the outer edge affects the results. Discuss your results. [15 Points]

An automated water dispenser fills packets with one liter of water on average, with a standard deviation of 5 milliliter. the manual says that after a year of operation the dispenser should be tested to see if it needs recalibration. a year later a number of filled packets are set aside and measured separately. it is found that the average packet now contains about 0.995 liters. does the dispenser need calibration? explain your answer.
