Draw the free body diagrams for sub-structures ABHIG and HJLNM. 3) Determine the forces acting on sub-structures ABHIG and HJLNM. 4) Once knowing the external forces acting on each sub-structure, we can further obtain the forces in each member of the sub-structures. Determine the forces in member ML and EH. L
