The adjacent graph shows the extension (∆l) of a wire of length lm suspended from the top of a roof at one end with a load W connected to the other end. If the cross sectional area of the wire is 10^–6 m², calculate the young\'s modulus of the material of the wire

The graph is drawn between the applied force F and the strain (x) for a thin uniform wire. The wire behaves as a liquid in the part

The value of force constant between the applied elastic force F and displacement will be

The diagram shown stress v/s strain curve for the materials A and B. From the curves we infer that

Which one of the following is the Young\'s modulus (in N/m²) for the wire having the stress-strain curve shown in the figure

The points of maximum and minimum attraction in the curve between potential energy (U) and distance (r) of a diatomic molecules are respectively

Two wires are made of the same material and have the same volume. However wire 1 has cross–sectional area A and wire 2 has cross–sectional area 3A. If the length of wire 1 increases by Δx on applying force F, how much force is needed to stretch wire 2 by the same amount?

The increase in length is l of a wire of length L by the longitudinal stress. Then, the stress is proportional to

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

Which is the most elastic?
