16. Let the cross-sectional area of the wire be A and the density of steel be ρ . The tensile stress is given by
τ/A where τ is the tension in the wire. Also, µ = ρA .Thus,
v max = τ max
µ
=
τ max /A
ρ
7 . 0
=
10 8 N / m 2
7800kg / m 3
×
=3 . 0 × 10 2 m / s
which is indeed independent of the diameter of the wire.
