a. Why can the support at A be considered only to provide a vertical reaction force in contrast to B where all three directions are restrained? (3 marks) b. Using the modelling assumptions described in part (a) calculate the vertical reactions to 3 sig. fig. at A and B. Take the mass of the tractor as 600kg acting at the location shown in Figure 3b. (7 marks) c. Looking at the roll-over protection bar shown in Figure 3c, give a justification for the distribution of load shown. (2 marks) 05 R 058 Figure 3c Load distribution of vertical reactions on roll-over protection d. Using one side of the roll-over protection frame, describe how it is supported and therefore what kind of beam it can be considered as (3 marks) e. Draw the free body diagram for one side of the frame (4 marks) 1. Draw a simplified shear force and bending moment diagram for the upper part of the frame from points C to D.
