Q1. For the structure shown below:
- Determine the reactions.
- Draw the bending moment diagram, shear force diagram and axial force diagram of each member. Draw the bending moments on the tension side.
Q2. Consider the cross-section shown below. All dimensions are in mm.
Determine:
- the location of the centroid.
- the second moment of area about a horizontal axis through the centroid.
Q3. Consider the roof truss shown below.
- Is this structure statically determinate ? Why (not) ?
- State for each member whether it carries compression, tension or zero axial force. Support your answers with clearly drawn free body diagrams showing all relevant forces.
