Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Blanking Force (F) = L × t × τ
Where,
L = Perimeter of blank
t = Thickness of plate
τ = Shear strength of the material
Calculation:
Given:
τ = 300 MPa, d = 100 mm, t = 1.5 mm
Blanking Force (F) = L × t × τ
F = πdtτ
F = π × 100 × 1.5 × 300 = 141 kN
