369814 With rise in temperature, the Young's modulus of elasticity

369815 A wire of length \(L\) and radius \(r\) is clamped at one end. If its other end is pulled by a force \(F\), its length increases by \(l\). If the radius of the wire and the applied force both are reduced to half of their original values keeping original length constant, the increase in length will become

369816 Two steel wires of radii \({r}\) and \({2 r}\) are connected together end to end and tied to a wall, as shown.

The force stretches the combination by \(\frac{{27}}{4}\,mm\). How far (in \(mm\)) does the junction point \(A\) move?

369817 Youngs's modulus for perfectly plastic body is
