Prob. 5.2-21. An engine that weighs 3.5 kN is suspended from point A of the engine hoist shown in Fig. P5.2-21. The hydraulic lift is positioned so that the hoist boom AC is hor- izontal. (a) Determine expressions for the transverse shear force V₁(x) and the bending moment M₁(x) at an arbitrary section that is x distance to the right of the support point A. that is, for 0<x< 1.6 m. (b) What is the axial force F₂ in the section BC of the hoist boom? Neglect the weight and bend- ing of the members of the hoist frame. -1.6 m P5.2-21 -0.9 m C 1.2 m
