Adisk is rotating around an axis located at its center. the angular velocity is 0.6 rad/s and the angular acceleration is 0.3 rad/s^2. the radius of the disk is 0.2 m. what is the magnitude of the acceleration at a point located on the outer edge of the disk, in units of m/s?

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.
