A copper rod 2m long is stretched by 1mm. Strain will be -

Two wires one of copper and other of iron having same cross-section area and lengths 2 m and 1.5 m respectively are fastened end and stretched by a load 10 N. If copper wire is stretched by 2mm then find the total extension of combined wire, Y_(Cu)=1xx10^(11)N//m^(2) and Y_(Fe)=3xx10^(11)N//m^(2) .

A copper wire 2m long is stretched by 1mm . If the energy strored in the stretched wire is converted into heat, then calculate the rise in temperature of the wire.

When a copper wire of area of cross section 1 mm^(2) is stretched by a force of 10N. Then the work done per unit volume in stretching the wire is (Y=1.2xx10^(11)Nm^(-2))

A copper wire is stretched by one percent of its length. What is the energy stored per unit volume of the wire if Y for its material is 11 xx 10^10 N/m^2 .

A wire having Young's modulus 2 xx 10^(11)N//m^(2) is stretched by a force. If the energy stored per unit volume of the wire is 40 "joule"//m^(3) , then the stress produced in the wire is

When a wire is stretched by a force the strain produced in the wire is 2 xx 10^(-4) . If the energy stored per unit volume of the wire is 4 xx 10^(4) "joule"//m^(3) then the Young's modulus of the material of the wire will be,

The Young's modulus of the material of a wire is 2xx10^(10) N m^(-2) If the elongation strain is 1% then the energy stored in the wire per unit volume is J m^(-3) is

The Young's modulus of the meterial of a wire is 2xx10^(10) N m^(-2) If the elongation strain is 1% then the energy stored in the wire per unit volume is J m^(-3) is
