A. Draw a simple model of a pair of needle-nose pliers and label (only) the critical parameters for determining the reaction force at the tip for a given squeezing force from the hands. B. Draw a simple model of a pair of needle-nose pliers and label (only) the critical parameters for determining how hard they can be squeezed before the handle breaks near the hinge. Free-Body Diagrams: In each of the following problems, 2-7, draw a free-body diagram of the indicated element. In each case: Draw force arrows as vectors, i.e., a single arrow pointing in the correct direction and sense, and label it. . Determine the magnitude and direction of each force and/or moment on the free body. Where convenient, you may provide the force or moment in components, for example as F = W x+ 3 W y. Plan to re-draw your FBD after your analysis for clarity. THIS! F. 3-W NOT THIS: THIS: Few NOT THIS: HINGE W RIGID SUPPORT!!!!! ROPE 1 LINK 2.
