Learning Goal: To use the dot product to find the components of forces acting in arbitrary directions. A three-legged structure is shown below. It is attached to the ground at points B = (4.04, 0, 0) and C (-4.04, 0, 0) and connected to the ceiling at point A = (-4.92, 3.79, 4.87). The three legs connect at point D = (0, 3.23, 2.00), where two forces, F and P, act. Force F is given by F 9.60 i 13.5 j + 24.8 k N; P has magnitude 50.0 N and direction angles a=120.0°, ẞ= 49.0°, and y = 55.6° for the x, y, and z axes, respectively. (Figure 1) Part C - Determining the force along a member Determine the magnitude, FDA, acting along member DA, due to the applied force F = 9.60 i - 13.5 j + 24.8 k N.
