The needle-nose pliers are used to either cut objects at location A or grip objects at location B. Compute (a) the cutting force at A and (b) the gripping force at B in terms of the applied force F. Determine the magnitude of the pin reaction at O in both cases. Neglect the effects of the slight opening of the jaws to accommodate the gripped items. 51 mm 20 mm 86 mm Answers: (a) The cutting force at A: FA = F The pin reaction at O: FO = F (b) The gripping force at B: FB = F The pin reaction at O: FO = F
