Asingle-phase motor vibrates at a fre¬quency of 100 hz. what is the fre¬quency of the power line? b. a capacitor-run motor does not have to be set in a resilient mounting. why? c. a 4-pole, 60 hz, single-phase hysteresis motor develops a torque of 6 in·lb when running at 1600 rpm. calculate the hysteresis loss per revolution [j].

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.
