look up the modulus of elasticity of steel, about 220GPa.
Force= 220GPa*area*deltaL/L
mass*g=force
so mass= 220GPa*PI(.0033)^2*.14/1.6*9.8
check that.
What hanging mass will stretch a 1.6 meter long, 0.66cm diameter steel wire by 1.4cm.?
Need answer in kg. ( this is all that is in the question , no other hints given).
