Task 1a

Using the diagram of a beam provided (Figure 1), work out the reactions at each end and create a shear force diagram and bending moment diagram showing the maximum bending moment. 

Show all working out of calculations for reactions on beam and the following diagrams: 

• Shear force diagram 

• Bending moment diagram with all relevant working outs

Figure 1

• Note: Convert a UDL to a point load, for example 2kN/m x 8metres = 16kN of which the point load will be in the middle of the UDL location.

Task 1b

Using the diagram of an ‘I’ beam provided (Figure 2), work out the moment of inertia.

Show all working out of calculations for working out moment of inertia.
