Question

A 10mm diameter annealed steel wire is drawn through a die at a speed of 0.5 m/s to reduce the diameter by 20%. The yield stress of the material is 800 MPa

Neglecting friction and strain hardening, the stress required for drawing (in MPa) is

Solution

The correct option is B 357.0
Diameter of steel wire

di=10mm

v=0.5 m/s

Final diameter of wire

df=0.8×di=8mm

Drawing stress under ideal condition is given as,

σd=σyt×ln(didf)2

=800×2ln(108)

=357 MPa
