A steel rod of diamerer 1 am is clamped firmly at each end when its temperature is `25^(@)C` so that it cannot contract on cooling The tension in the rod at `0^(@)C` is approximately
`(alpha=10^(-5)//^(@)C,Y=2xx10^(11)Nm^(-2))`

A steel rod of diameter 10 mm is clamped firmly at each end when its temperature is 25^(@)C so that it cannot contract on cooling The tension in the rod at 0^(@)C is approximately (alpha=10^(-5)//^(@)C,Y=2xx10^(11)Nm^(-2))

A steel wire 2 mm is diameter is just stretched between two fixed points at a temperature of 20^(@)C . If the temperature falls to 10^(@)C , then the tension in the wire is (Coefficient of linear expansion of steel (alpha) is 11xx10^(-6)//""^(@)C and Y_(s)=2.1xx10^(11)N//m^(2) )

A steel rod of length 1 m and area of cross section 1 cm^(2) is heated from 0^(@)C to 200^(@)C without being allowed to extend or bend. Find the tension produced in the rod (Y=2.0 xx 10 ^(11) Nm ^(-1) , alpha = 10 ^(-5) ^(@)C ^(-1))

Two ends of a wire are rigidly clamped. If its temperature is decreased by 10^(@)C , find the change in the tension of the wire. Area of cross-section of the wire =0.01cm^(2) , alpha=16 times 10^(-6@)C^(-1), Y=20 times 10^(11) dyn.cm^(-2)

A steel wire 2mm in diameter is stretched between two clamps, when its temperature is 40^@C Calculate the tension in the wire, when its temperature falls to 30^@C Given, coefficient Y for steel = 21 xx 10^(11) dyn e//cm^2

A steel wire 2 mm in diameter is just stretched between two fixed points at a temperature of 20^(@)C. If the temperature falls to 10^(@)C, then the tension in the wire is (The coefficient of linear expansion of steel = 11xx10^(-6)//^(@)C and Y for steel 2.1 xx10^(11)N//m^(2))

A steel wire 2 mm in diameter is just stretched between two fixed points at a temperature of 20^(@)C. If the temperature falls to 10^(@)C, then the tension in the wire is (The coefficient of linear expansion of steel = 11xx10^(-6)//^(@)C and Y for steel 2.1 xx10^(11)N//m^(2))
