A uniform wire of length 10 m and diameter 0.6 mm is stretched by 6 mm with certain force. If the Poisson's ratio of the material of the wire is 0.3, then the change in diameter of the wire is

Diameter of a brass disc at 30^(@)C is 10 cm. What will be the increase in area of the disc at 70^(@)C ? alpha for brass =18 times 10^(-6@)C^(-1) .

At 30^(@)C the diameter of a brass disc is 8 cm. What will be the increase in surface area if it is heated to 80^(@)C ? alpha of brass =18 times 10^(-6@)C^(-1) .

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)

The coefficient of apparent expansion of a liquid in a brass vessel is 14.6 times 10^(-5@)C^(-1) . What will be the coefficient of apparent expansion of that liquid when it is in iron vessel? alpha for brass =18 times 10^(-6@)C^(-1) " and " alpha for iron =12 times 10^(-6@)C^(-1) .

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))
