A rail track made of steel having 20m is clamped on a railway line at its two ends as show in Fig. 7(d). 17. On a summer day due to rise in temperature by 22^(@)C , it is deformed as show in Fig. 7(d). 17 .Find displacement of the center (x) . Given cofficient of liner expansion of steel is 1.2xx10^(-5) .^(@)C^(-1) .

A steel tyre is 1 m in diameter at 10^@C . To what temperature it must be raised so that it may just slip on a wheel 1.005 m in diameter ? alpha for steel = 12 xx 10^(-6)//^@C .

A steel wire of length 1 m and mass 0.1 kg and having a uniform cross-sectional area of 10^(-6) m^(2) is rigidly fixed at both ends. The temperature of the wire is lowered by 20^(@)C . If the wire is vibrating in fundamental mode, find the frequency (in Hz). (Y_(steel)=2xx 10^(11) N//m^(2),alpha_(steel)=1.21 xx 10^(-5)//.^(@)C) .

A rod has been laid by using alternate rails of steel and aluminium each 12m long in a winter season when temperature is .-2^(@)C . The maximum temprature which can must be left be-tween advance rules of they are just to touch on a summer day (alpha_("steel") = 1.2 xx 10^(-5) ^(0)C^(-1) alpha_(Al) = 2.4 xx 10^(-5) ^(0)C^(-1)

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]
