A steel rail `30m` long is firmly attached to the road be only at its ends. The sun raises the temperature of the rail by `50^(0)C`, causing the rail to buckle. Assuming that the buckled rail consitst of two straight parts metting in the centre, calculate how much the centre of the rail rise? Given, `alpha_(steel) = 12 xx 10^(-6//@)C.

A steel rail 30 m long is firmly attached to the roadbed only at its ends. The sun raises the temperature of the rail by 5^@C , causing the rail to buckle. Assuming that the buckled rail consists of two straight parts meeting in the centre, calculate how much the centre of the rail rises. coefficient of linear expansion of steel is 12xx10^(-6)//K .

Assuming that the buckled rail consists of two straight parts meeting in the centre, calculate how much the centre of the rail rises. coefficient of linear expansion of steel is 12xx10^(-6)//K .

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 of length 1m , mass 0.1kg and uniform cross-sectional area 10^(-6)m^(2) is rigidly fixed at both ends. The temperature of the wire is lowered by 20^(@)C . If transverse waves are set up by plucking the string in the middle.Calculate the frequency of the fundamental mode of vibration. Given for steel Y = 2 xx 10^(11)N//m^(2) alpha = 1.21 xx 10^(-5) per ^(@)C

Railway tracks are laid with gaps for expansion. The gap between the steel rails 20 m long is 1.2 cm at 10^@C . The temperature at which the steel rails just touch each other is ( prop steel = 12 xx 10^-6//^@C)

A rail track made of steel having length 10 m is clamped on a railway line at its two ends on a summer day due to rise in temperature by 20^@C, it is deformed as shown in fig. Find x (displacement of the centre) if alpha_(steel) = 1.2 xx 10^(-5)//^@C.

A rail track made of steel having length 10 m is clamped on a railway line at its two ends on a summer day due to rise in temperature by 20^@C, it is deformed as shown in fig. Find x (displacement of the centre) if alpha_(steel) = 1.2 xx 10^(-5)//^@C.

A heavy brass bar has projections at its ends as shown in the figure. Two find steel wires, fastened between the projections, are just taut (zero tension) when the whole systeam is at 0^(0)C . What is the tensile stress in the steel wires when the temperature of the systeam is raised to 300^(0)C ? Given that alpha_("brass") = 20 xx 10^(-6 ^(@))C^(-1) alpha_("steel") = 12 xx 10^(-6@)C^(-1) Y_("steel") = 2 xx 10^(11) Nm^(-2)

A steel tyre of 1.2 m inner diameter at 20^@C is to be fitted on a cartwheel of 120.33 cm diameter of the tyre. Calculate the temperature to which the steel tyre is to be raised so that it will just slip on the wheel. (alpha_(Steel) = 11 xx 10^-6//^@C)
