If length of wire is 1 m and cross-sectional area 5×10-5 m², when wire streched through 1 mm by a force of 10,000 N. Young's modulus of wire would be

A student performs an experiment to determine the Young’s modulus of a wire, exactly 2 m long, by Searle’s method. In a particular reading, the student measures the extension in the length of the

A rod of length L having uniform cross-sectional area A is subjected to a tensile force P as shown in the figure below. If the Young’s modulus of the material varies linearly from E1 to E2 along the

A mould having dimensions 100 mm × 90 mm × 20 mm is filled with molten metal through a gate as shown in the figure. For height h and cross-sectional area A, the mould filling time is t1. The height

A piece of copper wire has twice the radius of a piece of steel wire. The Young s modulus for steel is twice that for the copper. One end of the copper wire is joined to one end of the steel wire so t

If a 1 m long steel wire having area 5 * 10-5 is stretched through 1 mm by force of 10, 000 N then young modulus of wire is
