Calculate the punch force F (N) required to complete blanking. Circle with diameter of 20.9 mm must be cut out of the material with 7.9 mm in thickness and 322 MPa tensile strenght.
where L - the total length sheared, mm; s - thickness of material, mm; τ1 (tau1) - shear strength of material, MPa; Rm - tensile strength of material, MPa.
Relative error +/- 1% allowed. Circle circumference is L=pi()*d.

Find the force (F) needed for guillotine cutter to chop metal sheet. The thickness of material is 2 mm and tensile strength is 240 MPa. The angle between the blades of the cutter φ is 7 degrees.
where s - thickness of material, mm; Rm - tensile strength, MPa; τ1 (tau) - material's shear strength, MPa; φ (fi) - the angle between the blades of the cutter (usually 6-8 degrees).
Provide answer in Newtons.
