Determine the minimum necessary clearance height of the overpass and the resultant elevation of the bottom of the overpass over the PVI. Ignore the cross-sectional width of the overpass. b) Assuming that the curve is designed with the minimum required length of curve, and that the PVC is located at station 75 00, determine the stations of PVI and PVT.

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.
