A metal rod of length 'L' and cross-sectional area 'A' is heated through `'T'^(@)C` What is the force required to prevent the expansion of the rod lengthwise ?

An iron bar whose cross sectional area is 4cm^(2) is heated from 0^(@)C and 10^(@)C . The force required to prevent the expansion of the rod is [ Y of Iron = 2 xx 10^(12) "dyne" // cm^(2) alpha of Iron = 12 xx 10^(-6 //@) C ]

A metallic rod of length l cm and cross-sectional area A cm^(2) is heated through t^(@)C . After expansion if a mechanical force is applied normal to its length on both sides of the rod and restore its original length, what is the value of force? The young's modulus of elasticity of the metal is E and mean coefficient of linear expansion is alpha per degree Celsius.

Calculate the compressional force required to prevent the metallic rod length l cm and cross-sectional area A cm^(2) when heated through t^(@)C , from expanding along length wise. The Young's modulus of elasticity of the metal is E and mean coefficient of linear expansion is alpha per degree Celsius

Calculate the compressional force required to prevent the metallic rod length l cm and cross-sectional area A cm^(2) when heated through t^(@)C , from expanding along length wise. The Young's modulus of elasticity of the metal is E and mean coefficient of linear expansion is alpha per degree Celsiuss

A steel rod of length 25cm has a cross-sectional area of 0.8cm^(2) . The force required to stretch this rod by the same amount as the expansion produced by heating it through 10^(@)C is (alpha_(steel)=10^(-5)//^(@)C and Y_(steel)=2xx10^(10)N//m^(2))
