Question 51 (Textile Technology & Fibre Science)
In a vibroscope, a cotton fibre of 25 mm length is clamped at one end, led over a knife-edge support, tensioned by a weight of 350 mg, and is inclined to vibrate at a fundamental resonant frequency of 2.6 kHz. The linear density of the fibre (in tex), accurate to two decimal places, is __0.19 to 0.21__.
Given in the question-
Linear density of fibre(in tex)=?
By unitary rule:
1 meter length have=0.000207 gm
1000 meter length have=0.000207*1000
