A metal string is fixed between rigid supports. It is initially at negligible tensin. Its Young modulus is `Y`, density `rho` and coefficient of thermal expansion is `alpha`. If it is now cooled through a temperature `=t`, transverse waves will move along it with speed

A metal bar of length L and area of cross-section A is clamped between two rigid supports. For the material of the rod. It Young's modulus is T and Coefficient if linear expansion is alpha . If the temperature of the rod is increased by Deltat^(@)C , the force exerted by the rod on the supports is

A metal rod of Young's modules Y and coefficient of thermal expansion alpha is held at its two ends such that its length remains constant. If its temperature is raised by t^(@)C , the linear stress developed in it is

A metal rod of Young's modules Y and coefficient of thermal expansion alpha is held at its two ends such that its length remains constant. If its temperature is raised by t^(@)C , the linear stress developed in it is

A metal rod of Young's modulus and coefficient of thermal expansion alpha is held at its two ends such that its length remains invariant. If its temperature is raised by t^(@)C, the linear stress developed it its is .....

Two metal rods of the same length and area of cross-section are fixed end to end between rigid supports. The materials of the rods have Young moduli Y_(1) and Y_(2) , and coefficient of linear expansion alpha_(1) and alpha_(2) . The junction between the rod does not shift and the rods are cooled
