You have five gears meshed to each other running in a line. The first gear Z=100, second gear Z=50, third gear Z=200, fourth gear Z=150 and fifth gear Z=200. The first gear turns clockwise at 100 revolutions per minute. What direction will gear number 5 runs and at what speed?​

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.
