Question

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
