Engineering Studies – H1 Civil Engineering – Mechanical Analysis
This topic investigates beams, their types, application and mechanical analysis. Shear stress calculations and bending moment analysis are key concepts.
- Beam shapes
- Calculating the reaction forces at the beam supports
- Beam applied loads – point loading
- Beam uniform distributed loads (UDL)
- Bending moments
- Shear stress, calculating shear force values at load points along a beam
- Shear force diagrams
- 2nd moment of area
- Define the difference between a beam and a truss.
- Describe common beam shapes and reasons for these shapes.
- What is equilibrium?
- What type of beam supports are used?
- Evaluate pined and roller supports and the force reactions created at these support points.
- What reasons might a beam experience applied point loads?
- How are the reactions at the supports calculated?
- Define shear stress.
- What is the unit of shear stress?
- How do you calculate the shear stress at loads points along a loaded beam?
- Why is a diagram used to display calculated results for shear stress?
- Define a bending moment.
- How do you calculate bending moment at points along a loaded beam?
- What are the units of a bending moment?
- Why might a beam with a ‘UDL’ have a bending moment when no external loads are being applied?
- Explain the concept of the ‘neutral axis’.
- The ‘second moment of area’ value indicate what property?
