A bimetallic strip of thickness d and length L is clamped at one end at temperature t_(1) . Find the radius of curvature of the strip if it consists of two different metals of expansivity alpha_(1) and alpha_(2) (alpha_(1) gt alpha_(2) ) when its temperature rises to t_(2) "^(@)C .

There are two rods of length l_1 l_2 and coefficient of linear expansions are alpha_1 and alpha_2 respectively. Find equivalent coefficient of thermal expansion for their combination in series.

A bimetallic strip is formed out of two identical strips one of copper and the other of brass. The coefficients of linear expansion of the strip goes up by DeltaT and the strip bends to from an arc of radius of curvature R. Then R is.

A bimetallic strip is formed out of two identical strips one of copper and the other of brass. The co-efficients of linear expansion of the two metals are alpha_(C) and alpha_(B) . On heating, the the strip bends to form an are of radius of curvature R . Then R is

Two identical thin metal strips one of aluminium and the other of iron are riveted together to form a bimetallic strip. The temperature is raised by 50^(@)C . If the central planes of the two strips are separated by 2nm and the coefficients of thermal expansion of aluminium and iron are respectively 30 xx 10^(-6)//^(@)C and 10 xx 10^(-6)//^(@)C the average radius of curvature of the bimetallic strip is about

The co-efficient of thermal expansion of a rod is temperature dependent and is given by the formula alpha = aT , where a is a positive constant at T "in"^(@)C . if the length of the rod is l at temperature 0^(@)C , then the temperature at which the length will be 2l is

A bimetallic strip of thickness 2 cm consists of zinc and silver rivetted together. The approximate radium of curvature of the strip when heated through 50^(0)C will be : (linear expansivity of zinc and silver are 32 xx 10^(-6//@)C and 19 xx 10^(-6//@)C respectively)
