4.2. Mathematics

Try these first

1. 1.

   What are dead loads?

   Hint

   Consider what contributes to the building's weight.

2. 2.

   Name one type of live load.

   Hint

   Think about what moves in and out of a building.

3. 3.

   What is the primary difference between dead loads and live loads?

   • Dead loads are static
   • while live loads are dynamic.
   • Both are static.
   • Live loads cause structural failure.

   Hint

   Think about what stays the same versus what changes.

4. 4.

   True or False: Load intensity is the load spread over the entire structure.

   • True
   • False

   Hint

   Consider how load is measured.

5. 5.

   A contractor is designing a new high-rise building. They need to account for dead loads of the building materials totaling 500,000 N. If the live loads are expected to reach 200,000 N at maximum capacity, what steps should the contractor take to ensure safety against these loads?

   Hint

   Think about what calculations and designs are necessary.

6. 6.

   An engineer has designed a bridge to support a total load of 1,500,000 N. The bridge must withstand dynamic live loads that can vary. What considerations should be made for live loads compared to dead loads?

   Hint

   Reflect on the differences between static and dynamic forces on structures.
