2.2.1 A loss-free generator supplies 50 MW to an infinite bus, the steady- state limit of the system been 100 MW. Determine whether the generator will
remain in synchronism if the prime mover input is abruptly increased by
30 Mw.​

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.
