600 tons
400 tons
1000 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?
