Q: A copper wire of diameter d is stretched by a load hanging vertically from its lower end . The strain of the wire is 8.0x10^-4 . What's the strain in another copper wire of the same length but of diamteter 2d ?
A: 2x10^-4
Q: A light rod of length L hangs from the lower ends of two vertical wires M and N which are of the same natural length and diameter but ve differrent Young's moduli E1 and E2 respectively . A load is placed on the rod at a distance x from the wire M, so that the rod remains horizontal . What's the value of x in terms of L, E1 and E2 ?
A: (E2L)/ (E1+E2 )

I would be glad anyone solve this as soon as possible . It would be great explain diagram , equations , steps by steps . Tnx . There ll be more questions.
