The dimensions of four wires of the same material are given below. In which wire the increase in the length will be maximum?

A steel wire 2 m long is suspended from the ceiling. When a mass is hung at its lower end, the increase in length recorded is 1 cm. Determine the strain in the wire.

The edges of an aluminmum cube are $$10\ cm$$ long. One face of the cube is firmly fixed to a vertical wall. A mass of $$100\ kg$$ is then attached to the opposite face of the cube. Shear modulus of aluminium is $$25\times 10^{9} Pa$$, the vertical deflection in the face to which mass is attached is

A wire is stretched 1 mm by a force of 1 kN. How far would a wire of the same  material and length but of four times that diameter he stretched by the same  force?

A steel wire is stretched by 1 kg wt. If the radius of the wire is doubled,  its Young's modulus will:

 Plastic deformation results from the following 

A rubber ball of bulk modulus B is taken to a depth h of a liquid of density p. Find the fractional change in the radius of the ball. 

A thin metal sheet is being bent by or pounded in to a new shape. The process of being elastic to plastic behaviour is known as 

An elastic spring is given a force of 1000 N over an area of $$0.2 m^2.$$

The plasticity behaviour of a material determines the
