Derive cutting forces
WebDec 30, 2024 · Solution: When the hanging object is attached to the wire, the force at the end of the wire acting on the object exactly balances the gravitational force. Therefore by Newton’s Third Law, the tensile force stressing the wire is We can calculate the strain on the wire from Hooke’s Law (Equation (26.2.3)) and the value of Young’s modulus for steel .
