A threaded nut of $$M16, $$ $$ISO$$ metric type having $$2$$ $$mm$$ pitch with a pitch diameter of $$14.701$$ $$mm$$ is to be checked for its pitch diameter using two or three numbers of balls or rollers of the following sizes

A part shown in the gig is machined to the sizes given below

With $$100\% $$ confidence, the resultant dimension $$W$$ will have the specification

Quality screw threads are produced by

A cylinder is turned on a lathe with orthogonal machining principle. Spindle rotates at $$200rpm$$. The axial feed rate is $$0.25$$ $$mm$$ per revolution. Depth of cut is $$0.4mm.$$ The rake angle is $${10^ \circ }.$$ In the analysis it is found that the shear angle is $${27.75^ \circ },$$

The thickness of the produced chip is
