Show, graphically, the relation between stress and strain if a steady load is suspended at the lower end of a long wire.

What is the relation between relative lowering of vapour pressure of the solution and mole fraction of solute ?

Show graphically the nature of intermolecular forces when the distance between the molecule decreases.

If the radius of the octahedral void is r and radius of the atoms in close packing is R, derive a relation between r and R. Draw a diagram showing octahedral void and derive the relation between r and R.

An aluminium wire and a steel wire both of the same length and cross-section are joined end to end . The composite wire is hung from a rigid support and a load is suspended from the free end . If the increase in length of the composite wire is 2.7 mm, find the increase in length of each wire. Y_al = 7 xx 10^10 N/m^2 and Y_steel = 2 xx 10^11 N/m^2 .

Find the Young's modulus,stress and strain for a wire 2m long and 1 mm in diameter which when stretched by a force of 2 kg wt extends by 2mm .g=9.8 m/s^2 .
