Aim Of Concept:
- To provide the students an understanding of linear static analysis of determinate and indeterminate aircraft structural components.
- To introduce the advanced concepts in the stress analysis of beams.
- To impart knowledge and enable the student work out a variety of problems in structural analysis applying energy principles.
- To impart knowledge on column theory and practical column design.
- To allow the student to differentiate between various failures theories and appropriately apply a failure theory in design.
