The thickness of a metallic sheet is reduced from an initial value of 16 mm to a final value of 10 mm in one single pass rolling with a pair of cylindrical rollers each of diameter of 400 mm. The bite angle in degree will be
-
- 5.936
- 7.936
- 8.936
- 9.936
- 5.936
Correct Option: D
tanα = √(t1 - t2) / R = √(16 - 10) / 200
tanα = 0.173
∴ Bite angle, α = tan-1(0.173) = 9.936°
