Name the property of a material by which it opposes the deformation.

One end of a wire of length $L$ and weight $W$ is attached to a ceiling,and the other end is attached to a weight $W_1$. If the cross-sectional area of the wire is $S$,what is the stress at a distance $3L/4$ from the lower end of the wire?

Which one of the following is the weakest kind of bonding in solids?

The breaking stress for a wire of radius $r$ of a given material is $F \ Nm^{-2}$. The breaking stress for a wire of the same material of radius $2r$ will be:

The shear strain is possible in .............

Is it possible to double the length of a metallic wire by applying force over it?
