When a wire is stretched to double it.s length a) Radius is halved b) Strain is unity c) Stress is equal to Youngs modulus d) Stress is unity

A steel wire is stretched by 5 kg wt. If the radius of the wire is doubled its Young's modulus

Two wires of same radius and length are subjected to the same load. One wire is of steel and the other is of copper. It the Young's modulus of steel is twice that of copper, the ratio of elastic energy stored per unit volume in steel to that of copper wire is

A copper wire and a steel wire of radii in the ratio 1:2, lengths in the ratio 2:1 are stretched by the same force. If the Young's modulus of copper = 1.1 xx 10^11Nm^(-2) find the ratio of their extensions (young's modulus of steel = 2 xx 10^11 N//m^2) .

Show that stress required to double the length of wire (or) to produce 100% longitudinal strain is numerically equal to Young's modulus.

A steel wire of mass 3.16Kg is stretched to a tensile strain of 1xx10^(-3) . The elastic deformation energy if density rho= 7.9g/cc and Y=2 xx 10^11N//m^2

A uniform rectangular block of mass 50 kg is hung horizontally with the help of three wires A, B and C each of length and area of 2 m and 10 mm^2 respectively as shown in the figure. The central wire is passing through the centre of gravity and is made of a material of Young's modulus 7.5 xx 10^10 Nm^(-2) and the other two wires A and C symmetrically placed on either side of the wire B are of Young's modulus 10^11 Nm^(-2) . The tension in the wires A and B will be in the ratio of
