The coefficient of linear expansion of iron is `0.000011.^(@)C`. An iron ro is 10 metre long at `27^(@)c`. The length of the rod will be decreased by 1.1 mm when the temperature of the rod changes to

The co-efficient of linear expansion of iron is 11//180 of volume coefficient of expansion of mercury which is 18 xx 10^(-5) // ^(0)C . An iron rod is 10m long at 27^(@)C . The length of the rod will be decreased by 1.1mm then the termperature the rod changes by

If the coefficient of linear expansion of iron is 1.20xx10^-5K^(-1) and diameters of the wooden and the iron rings are 1.472m and 1.398m , then calculate the temperature to which the iron ring has to be heated from 27^(@) C, so that the iron ring fits over the wooden ring.

An iron rod and another of brass, both at 27^@C differ in length by 10^-3 m. The coefficient of linear expansion for iron is 1.1xx10^(-5)//^(@)C and for brass is 1.9xx10^(-5)//^(@)C . The temperature at which both these rods will have the same length is

An iron rod and another of brass, both at 27^@C differ in length by 10^-3 m. The coefficient of linear expansion for iron is 1.1xx10^(-5)//^(@)C and for brass is 1.9xx10^(-5)//^(@)C . The temperature at which both these rods will have the same length is

A rod is fixed between two points at 20^(@)C . The coefficient of linear expansion of material of rod is 1.1 xx 10^(-5)//.^(C and Young's modulus is 1.2 xx 10^(11) N//m . Find the stress develop in the rod if temperature of rod becomes 10^(@)C

A metal rod having a coefficient of linear expansion of 2 xx 10^-5 /^@C has a length of 100 cm at 20^@C . The temperature at which it is shortened by 1 mm is

A composite rod is made by joining a copper rod, end to end, with a second rod of different material but of the same area of cross section. At 25^(@)C , the composite rod is 1 m long and the copper rod is 30 cm long. At 125^(@)C the length of the composite rod increases by 1.91 mm . When the composite rod is prevented from expanding by holding it between two rigid walls, it is found that the constituent rods have remained unchanged in length inspite of rise of temperature. Find young's modulus and the coefficient of linear expansion of the second rod (Y of copper =1.3xx10^(10) N//m^(2) and a of copper =17xx10^(-6)//K ).
