Which of the following is least valid when pulling a wire
through a die to reduce its cross section?
The pulling force is limited by the yield strength of the
wire.
Use of lubrication can reduce the drawing force.
The die design influences the amount of redundant work
done on the wire.
Surface finish of the drawn wire is worsened due to work
hardening.
