6. Statics

Try these first

1. 1.

   What is a dead load? Give an example.

   Hint

   Think about what is fixed in place within a building.

2. 2.

   Name one type of environmental load.

   Hint

   Consider natural phenomena that affect structures.

3. 3.

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

   • Dead loads are static; live loads are dynamic.
   • Live loads are permanent; dead loads are temporary.
   • Both are always fixed.

   Hint

   Think about the things that do not change versus those that do.

4. 4.

   True or False: Environmental loads can change based on seasonal conditions.

   • True
   • False

   Hint

   Consider how weather affects structures differently.

5. 5.

   A bridge is expected to carry a maximum live load of 5,000 lbs. If the bridge has a dead load of 2,500 lbs, what is the total maximum load on the bridge?

   Hint

   Combine the two types of loads for the total.

6. 6.

   During a storm, a building experiences a wind load of 50 psf on one side with dimensions of 80 ft by 120 ft. What is the total force exerted by the wind on that wall?

   Hint

   Calculate the area first before multiplying by wind pressure.
