The breaking stress of a wire is `7.2xx10^(8)N//m^(2)` and density is `78xx10^(2) kg//m^(3)`. The wire is held vertically to the rigid support. The maximum length so that the wire does not break is

The breaking stress of the material of a wire is 6xx10^(6)Nm^(-2) Then density rho of the material is 3xx10^(3)kgm^(-3) . If the wire is to break under its own weight, the length (in metre) of the wire made of that material should be (take g=10ms^(-2) )

For steel the breaking stressis 6xx10^(6)N//m^(2) and the density is 8xx10^(3)kg//m^(3) . The maximum length of steel wire, which can be suspended witout breaking under its own weight is [g=10m//s^(2)]

The breaking stress of steel is 7.9xx10^9 Nm^(-2) and density of steel is 7.9xx10^3 kgm^(-3) and g = 10ms^(-2) . The maximum length of steel wire that can hang vertically without breaking is

A wire has breaking stress of 6xx10^(5)N//m^(2) and a densiity of 3xx10^(4)kg//m^(3) . The length of the wire of the same material which will break under its own weight, (if g=10m//s^(2) ) is

The breaking force of wire is 10^(4) N and radius is 1xx10^(-3) m. If the radius is 2xx10^(-3) m, then the breaking force will be
