In an experiment, brass and steel wires of length 1 m each wit area of cross section `1mm^(2)` are used. The wires are connected in series and one end of the combined wire is connected to a rogid support and other end is subjected to elongation. The stress required to produce a net elongation. the
In an experiment, brass and steel wires of length 1 m each with areas of cross section 1mm^(2) are used. The wires are connected in series and one end of the combined wire is connected to a rigid support and other end is subjected to elongation. The stress required to produce a net elongation of 0.2 mm is, [Given, the Young’s Modulus for steel and brass are, respectively, 120 xx 10^(9) N//m^(2) and 60 xx 10^(9) N//m^(2)
In an environment, brass and steel wires of lengh 1 m each with areas of cross section 1mm^(2) are used. The wires are connected in series ankd one end of the combined wie is connected toa rigid support and other endis subjected to elongation. The stress (in Nm^(-2) ) requird to produce a net elongation of 0.2 mm is [Given the Young's modulus for steel and brass are respectively 120xx10^(9)N//m^(2) and 60xx10^(9)N//m^(2) )
A 20kg load is suspended by a wire of cross section 0.4mm^(2) . The stress produced in N//m^(2) is
A 20kg" load is suspended by a wire of cross section 0.4mm^(2).The stress produced in N/m ' is
On increasing the length by 0.5 mm in a steel wire of length 2 m and area of cross section 2 mm^2 , the force required is [Y for steel =2.2xx10^11(N)/(m^2) ]
A steel wire of length 2.5 m and area of cross section 1.25 mm^(2) , when it is stretched by a force of 40 N and Y for steel is 2xx10^(11)N//m^(2) . The extension produced in a steel wire is
A copper wire and a steel wire of the same length and same cross-section are joined end to end to form a composite wire. The composite wire is hung form a rigid support and a load is suspended form the other end. If the increses in length of the composite wire is 2.4mm . then the increases in lenghts of steel and copper wires are
A wire of length L and area of cross-section A, is stretched by a load. The elongation produced in the wire is I. If Y is the Young's modulus of the material of the wire, then the torce corstant of the wire is
