8 important questions on Paragraph
What are Concentrated loads?
- Point load: F in Newton
- Moments: M in Nm
What are Distributed loads?
- Distributed line load: q in N/m (force/length)
- Distributed plane load: p in N/m^2 (force/area)
When is the structure considered to be in equilibrium?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What are the three conditions for an equilibrium of 2-dimensional structures?
- sum of the forces in x-direction is zero: ΣFx = 0
- sum of the forces in z-direction is zero: ΣFz = 0
- sum of the moments about the y-axis or any arbitrary line, parallel to the y-axis is zero (or about a line, perpendicular to the plane of drawing) ΣMline // y-axis = 0
What comes from the external equilibrium of the structure?
What are examples of lateral forces?
- Earthquake
- Pressure
What are the internal force types that can occur in a structure?
What are cross-sectional forces?
