The cross-sectional area of a steel rod of length 25 cm is 0.8 cm^(2) . What tension will be required to incresase the length of the rod, equal to the increase due to its rise in temeprature by 10^(@)C ? For steel, Y=2 times 10^(12)dyn*cm^(-2) " and " alpha=10^(-5@)C^(-1) .

The radius of a copper wire is twice that of a steel wire. One end of the copper wire is joined with one end of the steel wire and the same tensile force is applied on them . If the length of the copper wire increases by 1% , what will be the percentage increase in the length of the steel wire? Given Young's modulus of steel is twice that of copper.

Two ends of a steel rod are rigidly fixed with two supports. At 30^(@)C its area of cross-section is 4 cm^(2) .

[Young's modulus of steel =2.1 times 10^(12)dyn*cm^(-2) and its coefficient of linear expansion is 12 times 10^(-6@)C^(-1)]

Equal increase in length occurred in two wires, one is of steel of cross sectional area 3.0 xx10^-5 m^2 and another one is of copper of cross sectional area 4.0xx10^-5m^2 , by applying equal load on them. If Young's modulus of steel and copper are 2.0xx10^11 Nm^-2 and 1.0xx10^11Nm^-2 respectively, then the ratio of their initial lengths will be

Two rods of equal length and cross- sectional area have their Young's moduli Y_1 and Y_2 respectively. IF the rods are joined end to end, then the equivalent Young's modulus of the combined rod system is
