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. B Answers: F 54 mm 11 mm 78 mm A O F (a) The cutting force at A: FA = i F The pin reaction at O: Fo= i F (b) The gripping force at B: FB = i F The pin reaction at O: Fo= i F
