Level 4 Applied Technology
Sample Item
Your industrial services company has been hired to deliver a small but heavy gearbox. The container is too small to justify renting a large truck and too heavy for the company's pickup truck. You decide to rent a heavy-duty utility trailer and pull it with the pickup truck.
At which spot, labeled 1 – 5, on the trailer shown should you place the container to pull the load most easily and safely?
- 1
- 2
- 3
- 4
- 5
Why this is a Level 4 item:
- Examinees must use the principles of leverage and understand the interaction of forces on the tongue of the trailer.
- The problem involves two simple systems (the truck and the trailer) working together to create a moderately complex system.
- Examinees must apply basic principles (of mechanics) that may not be obvious.
- Examinees must understand the operation of a moderately complex system.
- Examinees must identify the best solution after eliminating other possibilities.
