A power system supplying a steady power of 100 MW via a radial feeder is found to be occasionally prone to a 107 MW power demand transient surge of 10 millisecond duration. Making any assumptions as necessary design an inertial mass unit capable of supply the transient. Expected: outline design, calculations and discussion of operation of the inertial mass system.

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.
