Question 54 (Textile Engineering & Fibre Science)
Determine the correctness or otherwise of the following assertion (a) & reason (r)
Assertion: The positive let off motion maintains the free length of warp and the tension on warp sheet at constant levels
Reason: The fluctuation of free warp length due to take up causes change in warp tension, which is sensed by the system, and the correction in both warp tension and in free warp length is carried out through the let off system automatically
| (A) | Both (a) and (r) are true and (r) is the correct reason for (a) |
| (B) | Both (a) and (r) are true and (r) is not the correct reason for (a) |
| (C) | Both (a) and (r) are false |
| (D) | (a) is true but (r) is false |
