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 (p) in MPa for the above process is related to extrusion ratio (r) as

where σm 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 K s 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).
    Correct answer is '2429.201'. Can you explain this answer?

    Af = 60 x 10 = 1000 mm2


    = 2429201.415 N
    f = 2429.201 kN
    Hence, the maximum force required at the start of extrusion is 2429.201 kN.
