Question 50 (Textile Engineering & Fibre Science)
Determine the correctness or otherwise of the following assertion (a) & reason (r)
Assertion: The strength of a pneumatically spliced joint a single cotton yarn results out of the load bearing capacity of the largely parallel fibres in the central section of the joint
Reason: The central section is surrounded by densely clustered groups of fibres, which are highly twisted and intermingled. On application of tensile load, these fibres slip and progressively grip the central section tightly, enhancing in the process their load bearing capacity
| (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 |
