When friction is not negligible and the die angle is considered small in a drawing process, how can the redundant drawing force be determined, utilizing the formulas associated with friction and redundant work?
A) The redundant drawing force is equal to the friction force divided by the die angle.
B) The redundant drawing force is the difference between the total drawing force and the friction force.
C) The redundant drawing force is the sum of the friction force and the die angle.
D) The redundant drawing force is proportional to the coefficient of friction and inversely proportional to the die angle.
