In the above problem, If the yield strength of steel is 2.5 xx 10^8 N m^-2 , what is the maximum weight that can be hung at the lower end of the wire?

(a) A steel wire of mass u per unit length with a circular cross section has a radius of 0.1 cm. The wire is of length 10 m when measured lying horizontal and hangs from a hook on the wall. A mass of 25 kg is hung from the free end of the wire. Assuming the wire to be uniform an lateral strains lt lt longitudinal strains find the extension in the length of the wire. The density of steel is 7860 kgm ^(-3) and Young's modulus =2 xx 10 ^(11) Nm ^(-2) (b) If the yield strength of steel is 2.5 xx 10 ^(8) Nm ^(-2), what is the maximum weight that can be hung at the lower end of the wire ?

A body of mass 500 g is fastened to one end of a steel wire of length 2m and area of cross-section 2m m^(2) . If the breaking stress of the wire is 1.25 xx 10^(7) N//m^(2) , then the maximum angular velocity with which the body can be rotated in a horizontal circle is

The tensile strength of steel is 5 xx 10^7 N m^-2 . Find the maximum length of the wire that can hang vertically , without breking it. Densityof steel is 8 xx 10^3 kg m^-3.

The elastic limit and ultimate strength for steel is 2.48 xx 10^(8) Pa and 4.89 xx 10^(8) Pa respectively. A steel wire of 10 m length and 2 mm cross sectional diameter is subjected to longitudinal tensile stress. Young’s modulus of steel is Y = 2 xx 10^(11) Pa (a) Calculate the maximum elongation that can be produced in the wire without permanently deforming it. How much force is needed to produce this extension? (b) Calculate the maximum stretching force that can be applied without breaking the wire.

A steel wire of mass mu per unit length with a circular cross-section has a radius of 0.1cm . The wire is of length 10m when measured lying horizontal, and hangs from a hook on the wall. A mass fo 25kg is hung from the free end of the wire. Assume the wire to be uniform and laterla strain lt lt logitudinal strain. If density of steel is 7860 kg m^(-3) and Young's modulus is 2xx10^(11) N//m^(2) then the extension in the length fo the wire is
