How Strong is Nylon? Take an iron stand with a clamp. Take samples of cotton, wool, nylon and silk threads of about 50cm in length. First tie cotton thread to the stand so that it hangs freely from it. At the free end, attach a CD as plate so that weights can be placed on it. Add weights starting from 10 grams one by one, until the thread breaks. Note down the total weight required to break the cotton thread. Repeat the same activity with the wool, silk and nylon threads.
NOTE: All the varieties of threads should be of same thickness.
