The adjacent figure is the part of a horizontally stretched net. section AB is stretched with a force of 10 N . The tensions in the sections BC and BF are

A steel wire 4 m in length and 2.4*10^(-7)m^2 in cross - section is stretched by a force of 36N . Calculate the stress and strain .

When a copper wire of area of cross section 1 mm^(2) is stretched by a force of 10N. Then the work done per unit volume in stretching the wire is (Y=1.2xx10^(11)Nm^(-2))

In the following figure, if the tension in the string AB is 51N, then the tension in the string BC will be :-

A wire of length 10 m and cross-section are 10^(-6) m^(2) is stretched with a force of 20 N. If the elongation is 1 mm, the Young's modulus of material of the wire will be

A wire whose cross-sectional area is 2 mm^2 is stretched by 0.1 mm by a certain load, and if a similar wire of triple the area of cross-section is stretched by the same load, then the elongation of the second wire would be

A wire whose cross-sectional area is 2 mm^2 is stretched by 0.1 mm by a certain load. If a similar wire of triple. the area of cross-section is stretched by the same load, the elongation of the second wire would be

A 4.0 m long copper wire of cross sectional area 1.2 cm^(2) is stretched by a force of 4.8 × 10^(3) N stress will be -
