Question 51 (Textile Engineering & Fibre Science)
A fabric with mass per unit area 250 g/m2 has flexural rigidity of 275 . The bending length (mm) of the fabric (rounded off to 2 decimal places) is __46.00 to 50.00__.
Given in the question–
Fabric mass per unit area(W)=250 g/m2
Bending length of the fabric(C)=?
G=W x C3 ,
Where, G is flexular regidity , C is bending length
275*10-6*103/9.8=250 x C3 (=10-6 N and 1 kg=1000 gm)
C=0.4823*10-1 *103 mm
C=0.4823 *102 mm
C=48.23 mm (Answer)
