2.1. For the force shown in Figure 2.1 a) Determine the x, y, and z components of F. (Marks 3) b) Express F in Cartesian vector form. (Mark 1) c) Determine the direction angles (a, B, and y) of force F with respect to x, y, and z axes and verify that the direction angles satisfy the requirement cos at cos B+ cos y=1. (Marks 3) d) Express F as a product of its scalar magnitude and a directional unit vector. i.e. F.UF (Marks 1) F=375 kN 120 Figure 2.1
