We want to draw a 0.3-inch diameter copper wire having a yield strength of 20,000 psi into 0.25-inch diameter wire. (a) Find the draw force, assuming no friction; (b) Will the drawn wire break during the drawing process? Show why.

Step 1
The cross-sectional area \( A \) of a wire with diameter \( d \) is given by: \[ A = \frac{\pi d^2}{4} \] For the initial wire with a diameter of 0.3 inches: \[ A_1 = \frac{\pi (0.3)^2}{4} \] For the final wire with a diameter of 0.25 inches: \[ A_2 = \frac{\pi Show more…

Wire is drawn through a draw die with an entrance angle of 15°. The starting diameter is 2.5 mm and the final diameter is 2.0 mm. The coefficient of friction at the work-die interface is 0.07. The metal has a strength coefficient K = 205 MPa and a strain hardening exponent n = 0.20. Determine the draw stress and draw force in this operation.

Wire is being drawn at a constant rate from a spool by applying a vertical force $P$ to the wire as shown. The spool and the wire wrapped on the spool have a combined weight of 20 Ib. Knowing that the coefficients of friction at both $A$ and $B$ are $\mu_{s}=0.40$ and $\mu_{k}=0.30,$ determine the required magnitude of force $\mathbf{P}$.
