A steel wire of uniform cross-section `1 mm^(2)` is heated to `70^(@)C` and stretched by tying it two ends rigidly. Calculate the change in tension on the wire when temperature falls form `70^(@)C` to `35^(@)C`

A steel wire of unifrom cross-section 1 mm^(2) is heated to 70^(@)C and strechted by tying it two ends rigidly. Calculate the change in tension on the wire when temperature falls form 70^(@)C to 35^(@)C

A steel wire , of uniform area 2mm^2 , is heated up to 50^@C and is stretched by tying its ends rigidly . The change in tension , when the temperature falls from 50^@C " to " 30^@C is (Take Y=2xx10^(11)Nm^(-2) , alpha=1.1xx10^(-5^@C-1))

A steel wire of uniform cross-sectional area 2mm^(2) is heated upto 50^(@) and clamped rigidly at two ends . If the temperature of wire falls to 30^(@) then change in tension in the wire will be , if coefficient of linear expansion of steel is 1.1 xx 10^(-5)//"^(@)C and young's modulus of elasticity of steel is 2 xx 10^(11) N//m^(2)

A wire of cross sectional area 3 mm^(2) is just stretched between two fixed points at a temperature of 20^(@)C . Then the tension in the wire when the temperature falls to 10^(@)C is, (alpha =1.2 xx 10^(-5) //""^(@)C, Y=2xx10^(11) N//m^(2))

A wire of uniform cross - section is suspended vertically from a fixed point , with a load attached at the lower end . Calculate the fractional change in frequency of the wire due to rise in temperature by t^(@) C . The coefficient of expansion of the wire is alpha .

A steel wire having cross-sectional area 2 mm^(2) is stretched by 20 N. Find the lateral strain produced in the wire

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 of length 20 cm and uniform cross-sectional area of 1 mm^(2) is tied rigidly at both the ends at 45^(@)C . If the temperature of the wire is decreased to 20^(@)C , then the change in the tension of the wire will be [Y for steel = 2 xx 10^(11 Nm^(-2) , the coefficient of linear expansion for steel = 1.1 xx 10^(-5)//.^(@)CC^(-1) ]
