A slightly tapring wire of length L and end radii 'a' and 'b' is subjected to stretching forces F, F as shown in

If Y is the Young's Modulus, calculate the extension prouduced in the wire.

The force-extension graph of an elastic wire subjected to a certain force is as shown in Figure. From the graph calculate the work done in stretching the wire.

Copper of fixed volume V is drawn into a wire of length l. When this wire is subjected to a constant force F, the extension produced in the wire is Deltal . If Y represents the Young's modulus, then which of the following graphs is a straight line?

A wire of length L and area of cross-section A, is stretched by a load. The elongation produced in the wire is I. If Y is the Young's modulus of the material of the wire, then the force constant of the wire is

A wire of length L and area of cross-section A, is stretched by a load. The elongation produced in the wire is I. If Y is the Young's modulus of the material of the wire, then the torce corstant of the wire is

A slightly conical wire of length l and radii, r_(1) and r_(2) is strecthced by two forces each of magnitude F applied parallel to length in opposide directions and normal to end faces. If Y denotes the Young's modulus then find the elogation of the wire (r_(2) gt r_(1)) .

A wire of length L and radius r is fixed at one end and a force F applied to the other end produces an extension l. the extension produced in another wire of same material of length 2L and radius 2r by a force 2F is
