engineering recuitment JSSC JE Mock Test 2023 Production Engineering (Manufacturing) Metal Forming Rolling
In a rolling operation, the thickness of a rectangular piece is reduced from t1 to t2. The radius of both the rolls are equal to R. The angle of bite (θ) will be given by:
1
\(\theta = {\cos ^{ - 1}}\left[ {1 - \frac{{{t_1} - {t_2}}}{{2R}}} \right]\)
2
\(\theta = {\cos ^{ - 1}}\left[ {\frac{{{t_1} - {t_2}}}{{2R}}} \right]\)
3
\(\theta = {\cos ^{ - 1}}\left[ {1 - \frac{{2R}}{{{t_1} - {t_2}}}} \right]\)
4
\(\theta = {\cos ^{ - 1}}\left[ {\frac{{2R}}{{{t_1} - {t_2}}}} \right]\)
