In shear cutting operation, a sheet of 5 mm thickness is cut along a length of 200 mm. The cutting blade is 400 mm long (see figure) and zero-shear (S = 0) is provided on the edge. The ultimate shear strength of the sheet is 100 MPa and penetration to thickness ratio is 0.2. Neglect friction. 400 S I Assuming force vs displacement curve to be rectangular, the work done (in J) is (a) 100 (c) 250 (b) 200 (d) 300
