Answer 1

Answer:

• Take an iron stand with a clamp and a cotton thread of about 65 cm length.
• Tie the thread to the clamp so that it hangs freely as shown in figure.
• At the free end suspend a pan so that weight can be placed in it.
• Add weight one by one till the thread breaks.
• Note down the total weight required to break the thread. This weight indicates the strength of the fibre.
• Repeat the same activity with threads of wool, silk and nylon.
• You will observe that the weight required to break the threads of wool, silk and^nylon is more than cotton. So, synthetic fibres are stronger than cotton.
