A cylindrical work-piece is subjected to a cold upset forging operation. The starting piece is 75 mm in height and 50 mm in diameter. It is reduced in the operation to a final height of 36 mm. The work material has a flow curve defined by K = 350 MPa and n = 0.17. Assume a coefficient of friction of 0.1. Determine the forging force at (a) the intermediate height of 62 mm, (b) the intermediate height of 49 mm,...

(15 pts) 6. A cylindrical part is forged in an open die. The starting diameter = 50 mm and height = 40 mm. Height after forging = 30 mm. Coefficient of friction at the die-work interface = 0.20. Yield strength of the low-carbon steel work material = 105 MPa; its strength coefficient = 500 MPa and strain hardening exponent = 0.25. Determine (a) the romarse force for the viviu point is reacha ... tegenkor Lici........ .he longer tha n (a)...

1/9 1 Piping system (14 points) Water is pumped from a reservoir to a large receiver vessel which is maintained at p4 6 bar (absolute) through the operation of the pump and a high pressure nitrogen supply that bleeds into the tank through a regulator. The water enters through an opening at the top of the vessel. A drain is provided at the low point in the system. Elevations are as shown. All valves are gate valves (k = 0.15)...
