A cylindrical rod of stainless steel is insulated on its exterior surface except for the ends. The steady-state temperature distribution is T(x)=a-bx/L, where a=305K and b=10K. The diameter and the length of the rod are D=20 mm and L = 100 mm, respectively. Determine the flux along the rod 푞"푥. Hint: The mass of the rod is m=0.248 kg.

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.
