Question

1.0 kg weight is suspended from a wire 10 m long & cross section area 2 mm2. If the strain be 0.001 % find the elongation of the wire & also calculate stress in the wire

plz answer as fast as possible​

Answer 1

Answer:

Answer:

4.9×1011N/m2

Given, Length of wire (L)=10 m cross sect ion (A)=2 mm2=2×10-6 m2 Loa d (m)=1 kg So, Force =mg=1×10=10 N00

and LAL×100=0.001(AL-elongation )LAL=

1x10-5

we know, young's modulus = strain Stre

SS

=(LAL)(AF)=1×10-52-10-610

Y=4.9×1011 N/m2
