Rods AB and CB are connected by a hinge B, whose axis is acted upon by two forces F 1 and F 2 as shown in the diagram. The bars are hinged at points A and C. Calculate the forces acting on the bars. Draw a calculation scheme, mark the bond reactions and mark the directions of the x and y axes in the scheme Write the equilibrium equations for a system of plane intersecting forces Solve the equations Check the solution analytically (choose another axis z and write the equilibrium equation) Check the calculations graphically: - Select the scale for drawing the force polygon • Draw the polygon of external forces and bond reactions to scale • Measure the lengths of the obtained sections, multiply by the scale and determine the values of the reactions
