1.How to find the force required in shearing sheet metal out by a cutter that does not cut at ninety degrees, but the end is inclined slightly at 90 + x degrees? The usual form is shearing stress× plate thickness× cutting length. In the new case, the tool impinges progressively from a single point over the entire area, so that the stress is concentrated at different regions at different times, thus reducing force. What would be the expression?
2. I am given an expression f×t×l÷s, where s is depth of shear, but it looks incorrect as well as dimensionally wrong.
