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
