5 original lesson summaries in this topic collection.
Topic overview
- Actions are dead, live or environmental; model them as point or distributed loads.
- Rollers give one reaction, pins two, fixed supports two plus a moment.
- Use ΣM about a support, then ΣFy, and check with a second moment equation.
- Negative reactions reverse the assumed direction; overhangs can produce downward reactions.
