the area of cross section of a wire is 1/100000 m^2 length of the wire is increased by 0.1% a tension of 1000N is produced.the young's modulus of the wire will be? ans: 1.10^11 N/m^2

A copper wire and an aluminium wire have length's in the ratio 3:2.diameters n the ratio 2:3 AND FORCES APPLIED IN THE RATIO 4:5 find the ratio of increase in length of the two wires.(Y FOR COPPER =1.1*1O^11 N/m^2,Y for aluminum=0.70*10^11 N/m^2). ans: 1)...
