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- (4.36 .0.0) and C =(-4.36.0.0) and connected to the ceiling at point A (--4.92 3.55 5.42) The three legs connect at point D - (0.2.89. 4.00), where two forces, F and P, act. Force F is given by F 6.00 1 - 16.53 +21.2 k NP has magnitude 35.0 N and direction angles a = 148.0.8 = 80.0 and y=60.0° for the x, y, and z axes, respectively. (Figure 1)
