Are my calculations and method here correct?

(b) Estimate the required press force for the bending operation, report your answer in units of N. Clearly state your assumptions including a sketch with labeled dimensions. (6 points) ko, Lt2 F = UTS W Using the rule of 8 for a V-Die (JEELIX, 2016), W = 8t = 8(5) = 40 mm As k = 1.25 for a V-die and o UTS = 440 MPa = 440 N/mm for AISI 1018 steel (Solitaire Overseas, 2024), F 1.25(440) (20) (5) 40 F = 6875 N
