A steel tape is calibrated at `20^(0)C`. When the temperature of the day is `-10^(0)C`, the percentage error in the measurement with the tape is `(alpha = 12 xx 10^(-6 //0)C)`

A steel taps is calibrated at 20^(0)C . When the temperature of the day is -10^(0)C , the percentage error in the measurement with the tap is (alpha = 12 xx 10^(-6 //0)C)

A steel tape is callibrated at 20^@ C . On a cold day when the temperature is -15^@ C , what will be the percentage error in the tape ?

A steel tape is correctly calibrated at 20^(@)C and is used to measure the length of a table at 30^(@)C . Find the percentage error in the measurement of length. [alpha_(steel) = 11 xx 10^(-5)//.^(@)C]

A second's pendulum clock havig steeel wire is calibrated at 20^(@) C. When temperature is increased to 30^(@) C, then calculate how much time does the clock [alpha_(Steel) = 1.2xx10^(-6^(@))C^(-1)

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) )

An iron ball of diameter 6cm and is 0.01 mm too large to pass through a hole in a brass plate when the ball and plate are at a temperature of 20^(0)C . The temperature at which (both for ball and plate) the ball just passes through the hole is (alpha_(iron) = 12 xx 10^(-6 //0)C, alpha_(brass) = 18 xx 10^(-6 //0)C)

A steel wire AB of length 100 cm is fixed rigidly at points A and B in an aluminium frame as shown in the figure. If the temperature of the system increases through 100^(@)C , then the excess stress produced in the steel wire relative to the aluminium? alpha_(Al) = 22 xx 10^(-6 //0) C and alpha_(steel) = 11 xx 10^(-6 //0) C young's Modulus of steel is 2 xx 10^(11) Nm^(-2) .

A steel scale is to be prepared such that the millimeter intervals are to be accurate within 6 xx10^(-5)mm . The maximum temperature variation form the temperature of calibration during the reading of the millimeter marks is (alpha = 12 xx 10^(-6)//"^(@)C)

An iron of length 50cm is joined at an end to copper rod to length 100cm at 20^(0)C. Find the length of the system at 100^(0)C and average coefficient of linear expansion of the systeam. (*_(iron) = 12 xx 10^(-6 //0)C and*_(copper) = 17 xx 10^(-6 //0)C.)

If a cylinder of diameter 1.0cm at 30^(@)C is to be slid into a hole of diameter 0.9997 cm in a steel plate at the same temperature, the minimum required rise in the temperature of the plate is: (Coefficient of linear expansion of steel = 12 xx 10^(-6//@)C )
