Load Calculation Basics

Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.

1. The total weight that a structure can safely support is called its  .

2. Live load refers to the temporary or movable weight on a structure, while dead load refers to the   weight of the structure itself.

3. To calculate the total load, you add the   load and the live load.

4. A bookshelf weighs 50 pounds. Each book weighs 2 pounds. If you put 30 books on the shelf, what is the total live load?

5. What is the dead load of a bridge if its total load capacity is 1000 tons and the maximum live load is 400 tons?

6. A table has a dead load of 25 kg. It is designed to hold a maximum live load of 75 kg. What is the total load capacity of the table?

7. Explain the difference between a live load and a dead load, and provide an example of each.

8. A construction beam can safely support a total load of 5000 N. If the beam itself weighs 1500 N, what is the maximum additional weight it can support?

9. A small bridge has a sign that says 'Maximum Load: 2 tons'. If a car weighs 1.2 tons and a truck weighs 3 tons, which vehicle(s) can safely cross the bridge? Explain your reasoning.
