This document appears to be an examination paper containing 8 questions divided into two parts (Part A and Part B) related to the subject of Structural Analysis - I. The questions cover various topics like determinate and indeterminate structures, degree of redundancy, strain energy, deflections of beams using different methods, analysis of arches, cables and continuous beams. Students are instructed to answer 5 full questions by selecting at least 2 questions from each part. Standard notations and formulas can be used. Diagrams of beam and arch structures are provided with the questions.
