A steel wire of length 4.7 m and cross-sectional area `3.0 × 10^(-5)` `m^2` stretches by the same amount as a copper wire of length 3.5 m and cross-sectional area of `4.0 × 10^(–5)` `m^2` under a given load. What is the ratio of the Young’s modulus of steel to that of
A rod of length 1.05 m having negligible mass is supported at its ends by two wires of steel (wire A) and aluminium (wire B) of equal lengths as shown in Fig.. The cross-sectional areas of wires A and B are 1.0 `mm^2` and 2.0 `mm^2` ,respectively. At what point along the rod should a mass m be suspended in order to produce (a) equal stresses and (b) equal strains in both steel and aluminium wires.
A 14.5 kg mass, fastened to the end of a steel wire of unstretched length 1.0 m, is whirled in a vertical circle with an angular velocity of 2 rev/s at the bottom of the circle.The cross-sectional area of the wire is 0.065 `cm^2`. Calculate the elongation of the wire when the mass is at the lowest point of its
A bar of copper of length 75cm and a bar of length 125cm are joined end to end. Both are of circular cross – section with diameters 2cm. The free ends of copper and steel are maintained at `100^oc and 0^oc` respectively. The surfaces of the bars are thermally insulated. What is the temperature of copper – steel junction? Thermal conductivity of copper `= 9.2xx10^(-2)k cal |m|'^oc|s` and that of steel is `1.1xx10^(-2) k
