A steel wire is rigidly fixed along diameter of aluminium ring of radius R as shown. Linear expansion coefficient of steel is half of linear expansion coefficient for aluminium thent he thermal stress developed in steel wire is:

What is the value of coefficient of linear expansion of aluminium?

Express thermal stress in terms of coefficient of linear expansion.

A steel wire AB of length 100 cm is fixed rigidly at points A and B in an aluminium frame as shown in the figure. If the temperature of the system increases through 100^(@)C , then the excess stress produced in the steel wire relative to the aluminium? alpha_(Al) = 22 xx 10^(-6 //0) C and alpha_(steel) = 11 xx 10^(-6 //0) C young's Modulus of steel is 2 xx 10^(11) Nm^(-2) .

The length of each steel rail is 10 m in winter. The coefficient of linear expansion of steel in 0.000012//^(@)C in summer. The gap to be left between the rails

A steel wire AB of length 85cm at 10^(@)C is fixed rigidly at points A and B in an aluminium frame as shown. If the temperature of the system is raised to 110^(@)C , what extra stress will be produced in the wire relative to aluminium frame. Assume that coefficient of linear expansion for aluminium and steel are 23xx10^(-6)//^(@)C and 11xx10^(-6)//^(@)C respectively and Young's moduls for steel is 2xx10^(11) pa.

Two Aluminium rods and a steel rod of equal cross-sectional area and equal length l_(0) are joined rigidly side by side as shown in figure. Initially the rods are at 0^(@)C . Find the length of the rod at the temperature theta if young's modulus of elasticity of the aluminium and steel are Y_(a) and Y_(s) respectively and coefficient of linear expansion of aluminum and steel are alpha_(a) and alpha_(s) respectively. |{:("Aluminium"),("Steel"),("Aluminium"):}|
