Engineering calculators
Tools
Use these to CHECK your hand calculations, not replace them. On the FE exam and on the job, you must be able to do every one of these by hand.
Beam analysis
Reactions, shear, moment and deflection diagrams for a simply supported beam.
Tip: steel E = 29,000 ksi (200 GPa). Look up I for W-shapes in the AISC tables, or use the Section Properties tool.
