Determine the components of all forces acting on member ABCD. The figure consists of member ABCD and member DEF.

a) As shown in the image given, a 69-kg crate is supported at equilibrium. The angles alpha=112 degrees. beta=145 degrees and the V =64.3 degrees. The coordinates of point D are (-2.2, 5.6, 3.2)m, and the spring constant k=1170N/m. Determine the stretch in the spring, in m which must be rounded to 3 places after the decimal point. Take g=9.81m/s^2. b) As shown in the image given, a 63-kg crate is supported at equilibrium. The angles alpha=112 degrees. beta=145 degrees and the V =64.3 degrees.
