MACHINE DESIGN - An 3-2e-1 PROBLEM 3-2e Statement: Draw free-body diagrams for the system of Problem 3-1e (pipe wrench). Assumptions: 1. A two-dimensional model is adequate. Solution: See Mathcad file P0302e. 1. A typical pipe wrench with a pipe clamped in its jaw is shown in Figure 3-2e(a). When a force F hand is applied on the wrench, the piping system provides an equal and opposite force and a resisting torque, T pipe . T F pipe hand hand a F (a) FBD of pipe wrench and pipe b d F ay F ax A F bt F bn α B hand F (b) FBD of pipe wrench only FIGURE 3-2e Free Body Diagrams for Problem 3-2e 2. The pipe reacts with the wrench at the points of contact A and B . The forces here will be directed along the common normals and tangents.
