For a body to be in equilibrium, two criteria must be met: =0 = 0 That is, the sum of the forces and the sum of the moments acting on the body must equal zero. Successful application of these equations of equilibrium requires that all known and unknown forces that act on the body be identified. The best way to account for these forces is to draw a free-body diagram. Figure 1 Figure 2 60 F2 12 B W Determine whether the following rigid bodies are in equilibrium and sort them accordingly. Drag the appropriate items to their respective bins. In equilibrium Part B Case 2 4N Not in equilibrium Case 1 A uniform beam weighs W and has the supports and loading shown in the figure. (Figure 1) Complete the free-body diagram of the beam by adding the missing forces acting on it. Draw the missing forces ending at the appropriate black dots. The location and orientation of the vectors will be graded. The length of the vectors will not be graded. F1 F L B. A B (+12).
