Q: The forces in the members of simple trusses may be analysed by
  • A. graphical method
  • B. method of joints
  • C. method of sections
  • D. All option are correct
Correct Answer: Option D - The forces in the members of simple trusses may be analysed by method of joints, graphical method and method of sections. In the method of joints, the axial forces in the members of a statically determinate truss are determined by considering the equilibrium of its joints. The method of sections usually proves to be more convenient when forces in only a few specific members of the truss are desired.
D. The forces in the members of simple trusses may be analysed by method of joints, graphical method and method of sections.
