Mechanical Engineering > GATE 2022 SET-2 > Extrusion
A cylindrical billet of 100 mm diameter and 100 mm length is extruded by a direct
extrusion process to produce a bar of L-section. The cross sectional dimensions of
this L-section bar are shown in the figure. The total extrusion pressure (π) in MPa
for the above process is related to extrusion ratio (π) as
where Ο0 is the mean flow strength of the billet material in MPa, l is the portion of the billet length remaining to be extruded in mm, d0 is the initial diameter of the billet in mm, and K0 is the die shape factor.
If the mean flow strength of the billet material is 50 MPa and the die shape factor is 1.05, then the maximum force required at the start of extrusion is ________ kN (round off to one decimal place).
