1.) A.) A cutting operation is performed on a piece of metal. The rake angle of the tool, α, is eight degrees. The tool penetrates the work to a depth of 8mm. The chips generated from this cut are 20mm thick. Calculate the shear plane angle, Φ, in the orthogonal model for this operation. Give your answer in degrees B.) For the same cutting operation, the cutting and thrust forces are measured. The cutting force is measured as 1600N, and the thrust force is measured as 1300N. The width of the cut is 4mm. What is the shear stress applied by the tool? Give your answer in MPa.

Learning Goal: A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids.An object is made from a uniform piece of sheet metal. The object has dimensions of a = 1.45 ft, where a is the diameter of the semi-circle, b = 3.24 ft, and c = 2.10 ft. A hole with diameter d = 0.500 ft is centered at (1.13, 0.725).
