Question 7

HLPaper 2

1. A team of design engineers is developing an outdoor viewing platform for a national park. Their design includes a cantilever beam for the overhanging section, uses mild steel components for structural support, and must meet strict safety regulations due to heavy visitor use. The team is evaluating structural behaviour through diagrams, materials testing, and past case studies of failures.

the engineers are using the following visuals in their analysis:

i.) Refer to Figure 1. Describe the direction and location of the key forces acting on the cantilever beam.

[2]

ii.) Refer to Figure 1. Explain two ways to increase the structural rigidity of the cantilever beam.

[2]

i.) Refer to Figure 2. Identify the region of the graph that represents plastic deformation.

[1]

ii.) Refer to Figure 2. Calculate the Young’s Modulus if a tensile stress of 300 MPa causes a strain of 0.01.

[1]

i.) Refer to Figure 3. Suggest one likely cause of the bridge’s structural failure.

[2]

ii.) Refer to Figure 3. Explain how applying a safety factor (SF) during design could have prevented this failure.

[2]

Question 8

HLPaper 1

What is the purpose of diagrammatically representing forces within structures?

Question 9

HLPaper 1

What structural concept is shown in this bridge truss diagram?

Question 10

HLPaper 1

When designing a ladder, what structure-related factor is most critical?
