Expert Answer:
Poisson's ratio is given as
When a deforming force is applied at the free ends of a suspended wire of radius R and length l, then the radius of the wire decreases by dR and its length increases by dl. So, a single force produces two types of strains:
Thus, 
The negative sign shows that if the length of the wire increases, then the radius decreases.

- State Hook's law on what factors does the modulus of elasticity of a subtance depend?
- Is strain is dimensions less
- The area of cross section of a wire and its length are 1mm^2 and 2mm respectively.how much will be the work done to increase its length by 0.1mm . Youngs modulus of material of the wire=2.0*10^11n/m^2
- a wire 1 mm diameter and 1 m long fixed at one end is stretched by 0.01 mm when a load of 10 kg is attached to its free end . calculate young's modulus of elasticity.
- Define shear modulus and show that shear stress = shear modulus x theta (where theta is the angular displacement of cylindrical from the vertical position of the cylinder) .
