Question

1. The number of equilibrium equations available in 2D is 6. 2. The Method of Sections results in a 2D rigid body equilibrium problem. 3. Indeterminate trusses can only be solved by Method of Joints, not Sections. 4. By definition, truss members must be pin connected & carry only axial load. 5. Shear Force is the first derivative of Bending Moment. 6. Distributed Load is the integral of Shear Force. 7. The maximum Bending Moment is always at the center of a simple span. 8. Point loads cause slope discontinuities in the Bending Moment Diagram. 9. Computation of elastic deflections relies on the assumption that angles are small enough that curvature can be approximated as M/EI. 10. Plastic deformations occur when strains beyond the yield strain are induced. 11. Bending without consideration of shear deformations can only result in a linear strain profile through the cross-section and thus a linear stress profile. 12. There is no shear stress on a principal plane, only axial stress. 13. The moment of inertia quantifies the distribution of area in a cross-section. 14. Shear stress in a flexural member is highest at the neutral axis. 15. The Conjugate Bending Moment is equal to the Slope in the real beam. 16. The conjugate restraint of a roller at the edge of a beam is a pin. 17. Braced Frames rely on the rotational rigidity of beam/column connections. 18. Moment Frames are more laterally flexible than Braced Frames. 19. The Flexibility Method can be used to compute redundant reaction forces. 20. Compatibililty equations equal in number to the degree of indeterminacy are needed to supplement equilibrium equations for an indeterminate analysis.
