Question

Write an activity to show that synthetic fibres are stronger than the cotton fibres.

Answer 1

Aim: To show that synthetic fibers are stronger than the cotton fibers

Activity

• Take a clamped iron stand and a cotton thread about 65 cm long.
• Tie the thread to the clamp, allowing it to hang freely.
• Suspend a pan at the free end so that weight can be placed in it.
• Add weight one at a time until the thread breaks.

Observation

• Make a note of the total weight needed to break the thread. This weight represents the fiber's strength.
• Repeat the process with wool, silk, and nylon threads.
• You'll notice that the weight required to break the threads of wool, silk, and nylon is greater than that of cotton.

Inference

• Synthetic fibres are therefore stronger than cotton since the weight required to break the threads of wool, silk, and nylon is greater.
