Three forces are applied to the eye bolt as shown in Figure Q2(a). If the coordinate direction angels for \( F_{3} \) are \( \alpha_{3}=120^{\circ}, \beta_{3}=45^{\circ}, \gamma_{3}=60^{\circ} \), determine : (i) the resultant of the three forces expressed in Cartesian vector form. (ii) the magnitude and the coordinate direction angles of the resultant force acting on the eye bolt. [5 Marks]
Expert Answer
The direction cosine of the force F3=800lb are ?3=120°,?3=45°,?3=60° So components of force F3 in x,y and z direction are given byF_2 F3x=F3×cos?(?3)=
