If the strain in a wire is not more than 1//1000 and Y =2xx10^(11)N//m^(2) Diameter of wire is 1 mm. The maximum weight hung from the wire is

The length of a wire is 10 m and the diameter is 2 mm . If the resistivity of substance of the wire is 2 xx 10^(-6) ohm . Then the resistance of the wire is

A rigid bar of mass 15 kg is supported symmetrically by three wires, each of length 2 m. The wires at the endpoints are made of copper and the middle one is made of steel. If the tension in each wire is the same, then the diameter of copper wire to the diameter of steel wire is ["Given, "Y_("copper")=1.1xx10^(11)"N m"^(-2) and Y_("steel")=1.9xx10^(11)"N m"^(-2)]
