Extracted text: Problem 2 Consider the casting of the 2mm thick object below shown in its top view. If one riser with D =H = 6.5 mm is needed for this casting, illustrate where the riser should be located to produce a sound casting. Is this possible with no chills? Hint: use your illustration to justify. If no risers were used, illustrate where the shrinkage defects would likely occur. Tip: Using Word's/Powerpoint's basic shapes will be helpful here. 12.5 mm 10 mm 6.2 mm
