Question:
A cotton yarn of 20 tex count is replaced by a polyester yarn such that both the yarns have the same diameter and the same packing density. Assuming densities of cotton and polyester fibres as 1.52 g/cm\(^3\) and 1.38 g/cm\(^3\), respectively, the count (tex) of the polyester yarn (rounded off to 2 decimal places) is ________________.

- A parallel fibre strand of 30 tex count is coming out from the nip of the front delivery rollers of a ring spinning machine. This strand is given twist to produce a yarn such that the length of the yarn becomes 0.95 times the length of the parallel fibre strand. If 600 turns are present in 1 m length of the yarn, then the twist factor (tpm-tex0.5) of the yarn (rounded off to the nearest integer) is____

- A ballistic type impact tester is shown below. The test specimen is connected to the bob of the pendulum of 10 N weight. The pendulum is released from a height of 1 m from the base, and this results in rupture of test specimen. Considering no frictional losses and neglecting the weight of the connecting rod, if the work of rupture of the specimen is 10 N-m, then the total swing angle (degree) that the pendulum makes during its travel (in integer) is
