Wire stock of initial diameter = 3.175 mm is drawn through two dies each providing a 0.20 area reduction. The starting metal has a strength coefficient = 276 Mpa and a strain hardening exponent = 0.15. Each die has an entrance angle of 12°, and the coefficient of friction at the work die interface is estimated to be 0.10. The motors driving the capstans at the die exits can each deliver 1.50 hp at 90% efficiency. Determine the maximum possible speed of the wire as it exits the second die.

Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.
