Calculate the reaction forces (bearing forces) in fixed bearing A and fixed bearing B. Calculate the forces in the rods KM and IL (indicate pressure or tension). Can rod LN be replaced with a rope? Justify the answer.
Figure 1. Trusses Figure 1. shows a truss composed of poles. It is stored in fixed bearing A and fixed bearing B. At the nodes N, P and R, forces act as shown in the figure. All joints are torque and friction free. Explain with a sketch, and without calculation, what type of load bar […]
