Part A - Finding the Cartesian components of a force described by direction angles Find the Cartesian components of force P acting in the x, y, andz directions given P = 20.0 N, a = 112.0°, B = 78.0°, and y = 25.4°. Recall that a is the angle between the vector and the x axis, B is the To use the dot product to find the components of forces acting in arbitrary directions. angle between the vector and the y axis, and y is the angle between the vector and the z axis. A three-legged structure is shown below. It is attached to the ground at points B = (4.88, 0, 0) and C = (-4.88, 0,0) and connected to the ceiling at point A = (-5.70, 3.46, 5.38). The three legs connect at point D = (0, 2.77, 2.00), where two forces, F and P, act. Force F is given by F = 8.40 i- 13.5 j+ 23.0 k N; P has magnitude 20.0N and direction angles a = 112.0°, B = 78.0°, and y = 25.4° for the x, y, and z axes, respectively.
