In the figure, two stamps (coins) with diameters D = 25 mm and d = 20 mm will be cut with a cutting die at the same time.Since the maximum cutting (molding) force that can be used is 2500 daN (F = 2500 daN), the maximum cut that can be cutfind the thickness (t) of the sheet material? The shear strength of the sheet material is 11 daN / mm2.
