This document appears to be an exam for the course Strength of Materials. It contains questions that ask students to: - Define terms like "Bulk modulus" - Derive expressions, like for the deformation of a member due to self weight - Calculate things like the stress induced in a member due to an applied load - Explain concepts such as principal stresses and maximum shear stress - Solve problems involving things like eccentric loading on a beam and buckling of columns The questions cover a wide range of topics in strength of materials including stress, strain, deformation, shear force and bending moment diagrams, principal stresses, and column buckling.
