Orthogonal turning of a mild steel tube with a tool of rake angle 10‑0‑ is carried out at a feed of 0.14 mm/rev. If the thickness of the chip produced is 0.28mm, the values of shear angle and shear strain will be respectively.
(a) 28020’ and 2.19 (b) 22020’ and 3.53
(c) 24030; and 4.19 (d) 37020’ 5.19
