Three wires `A,B,C` made of different materails elongated by `1.5,2.5,3.5mm`, under a load of `5kg`. If the diameters of the wires are the same, the most elastic material is that of

Two wires of the same length are made of different materials. Diameter of the one is 2 mm and that of the other is 4 mm. When these two wires are stretched by the same force, the first one's elongation is twice the second's.compare their Young's modulus.

A wire of length 2 ,m and radius 2 mm is stretched by 2.5 mm when a load of 5 kg is suspended from it Another wire of the same material put of length 1 m and radius 1 mm is attached below the load and a load of 3kg is suspended from this wire what is the total increase in length and what are the individual exensions of the wirs ?

Two wires A and B of the same dimensions are under loads of 4kg and 5.5kg respectively. The ratio of Young's moduili of the materials of the wire for the same elongation is

Two wires of the same length but of difference materials have diameter of 1mm and 3mm respectively.IF both of them are stretched by the same force,then the elongation of the first wire becomes thrice that of the second. Compare their Young's modull.

Three wires A,B,C made of the same material and radius have different lengths. The graph in the figures show the elongation-load variation. The longest wire is

5A current is divided into three parallel branches in a circuit.The ratio of the lengths of the wires in the branches is 2:3:4 and that of their diameters is 3:4:5 IF the wires are made of the same materials,find the current in each branch.

A metallic wire of length 3 m is stretched to produce an elongation of 2 mm. IF the diameter of the wire is 1mm, then find the decrease in its diameter due to this elongation.Poisson's ratio for the material of the wire is 0.24.

Four wires made of the same material are stretched by the same load. Their dimensions are given below. Which one will be elongated most?

A fuse wire with radius 1 mm blows at 1.5 A, The radius of fuse wire of the same material to blow at 3 A will be
