Two exactly similar wires of steel and copper are stretched by equal force. If the total elongation is 2 cm, then how much is the elongation in steel and copper wire respectively? Given, Y_("steel")=20xx10^(11)"dyne/cm"^(2),Y_("copper")=12xx10^(11)"Dyne/cm"^(2)

Two exactly similar wires of steel and copper are stretched by equal force. If the total elongation is 2 cm, then how much is the elongation in steel and copper wire respectively? Given, Y_("steel")=20xx10^(11)"dyne/cm"^(2),Y_("copper")=12xx10^(11)"Dyne/cm"^(2)

Two exactly similar wire of steel and copper are stretched by equal force. If the difference in their elongations is 0.5 cm, the elongation (l) of each wire is Y_(s)("steel") =2.0xx10^(11) N//m^(2) Y_(c)("copper")=1.2xx10^(11)N//m^(2)

Two exactly similar wires of steel (Y=20 xx 10^11 dy//cm^2) and copper (Y=12xx10^11dy//cm^2) are stretched by equal forces. If the total elongation is 1cm elongation of copper wire is

Two exactly similar wires of steel (y_(s)=20xx10^(11)"dyne"//cm^(2)) and copper (y_(c)=12xx10^(11)"dyne"//cm^(2)) are stretched by equal forces. If the total elongation is 1 cm, elongation of copper wire is

A copper wire and steel wire both have the same length and radius are joined end to end, when the composite wire is hung from a rigid support, and the load attached at the free end, the increase in the length is found to be 1cm. Find the increase in length of copper steel wire. (Y for copper = 1.2 xx 10^11 N//m^2 , Y for steel = 2.1 xx 10^11 N//m^2)
