Gyou are cold drawing a steel wire from 2 mm to 1.8 mm with a carbide die. the pulling velocity is 0.75 m/s. the coefficient () is 0.12. the die angle () is 4 degrees. for steel, k = 695 mpa and n = 0.32. there is no back stress in this process. a) determine if this draw is possible. b) determine the pulling force. c) determine the power.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
