The Nut Cracker Problem
A nut cracker is used to crack a nut. In it, a nut is held in two arms at a distance 2 cm from the hinge and its handle is at a distance 25cm from the hinge. If the force require to crack the nut is 30 Newton, find the minimum force required to crack the nut with nut cracker, in Newtons (Of course, it is less than 30 Newtons.).
