Question

2. In a rolling process, sheet of 30 mm is rolled to 20 mm thickness by using rolls of
diameter 300 mm. The angle subtended by the deformation zone at the roll centre is
(in radians) a. 0.004496
b. 0.2588
c. 14.835
d. 0.8134​

Answer 1

0.2588 dxfqddwdfssgsrdxas

Answer 2

Answer:

Angle of subtended

cos ø = 1-∆H/D

= 1-6/300

= 0.98

ø = 0.004496

Option (a)
