Question

An Iron stand with a thread hanging from the clam (diagram with explanation)​

Answer 1

Explanation:ake an iron stand with a clamp. Take a cotton thread of about 60 cm length. Tie it to the clamp so that it hangs freely from it. At the free end suspend a pan so that weights can be placed in it. Add weights 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, polyester, silk, and nylon. Tabulate the data. Arrange the threads in order of their increasing strength. You may use a hook or a nail on the wall for hanging the fibres and a polythene bag at the other end. In place of weights, you may use marbles (or pebbles) of similar size.
