1. 1.

   Define the term 'Beam'.

   Hint

   Think about shapes used in construction that hold up roofs.

2. 2.

   What is an 'Abutment'?

   Hint

   Consider the supports at either end of a bridge structure.

3. 3.

   What is a Beam?

   • A support for bridges
   • A type of load
   • A structural element that supports loads through bonding

   Hint

   Think about structures you see daily.

4. 4.

   True or False: An abutment is used to support the middle of a bridge.

   • True
   • False

   Hint

   Visualize a bridge and its support structures.

5. 5.

   Given a load distribution, calculate the stress on a beam of a specific size and material under load.

   Hint

   Use the bending stress formula, σ = My/I.

6. 6.

   Design a bridge abutment with given dimensions and load requirements. Include material choice and reasoning.

   Hint

   Consider local materials available and intended bridge type.
