An iron tyre is to be fitted onto a wooden wheel 1.0 m in diameter. The diameter of the tyre is 6 mm smaller than that of wheel the tyre should be heated so that its temperature increases by a minimum of (coefficient of volume expansion of iron is `3.6xx10^-5//^@C`)

An iron tyre is to be fitted onto a wooden wheel 1 m in diameter. The diameter of tyre is 6 mm smaller than that of wheel. The tyre should be heated so that its temperature increases by a minimum of (the coefficient of cubical expansion of iron is 3.6 xx 10^-5/^@C)

An iron tyre is to be fitted on a wooden wheel 0.1m in diameter. The miameter of the tyre is 6 mm smaller than that of the wheel. The tyre should be heated by a temperature of (coefficient of volume expansion or iron is 3.6xx10^(-5)//^(@)C )………….. .

Iron tyres are mounted on the wooden wheels of a tonga. Initially the diameter of the iron tyre is:

An iron ring 1.20 m in diameter is to be put on a wooden cart wheel. The diameter of this wheel is 1.0 cm greater than that of the ring. The temperature of the ring that must be raised before it slips on the wooden wheel is (Coefficient of linear expansion of iron = 12 xx 10^(-6)//^(@) C ).

An iron tyre of diameter 2 m is to be fitted on to a wooden wheel of diameter 2.01 m. The temperature to which the tyre must be heated , if alpha=11xx10^(-6).^@C^(-1) and room temperature is 20^@C , will be
