Challenge Problems
Push your limits with advanced challenges
A construction project is to take place at an altitude of 5,000 feet. If the manufacturer's standard horsepower rating is based on sea level conditions, calculate how much the engine's efficiency might drop and what compensatory measures can you suggest.
💡 Hint: Research the typical efficiency drop at specified altitudes.
You have a truck with a gravimetric capacity of 10 tons. If you decide to add sideboards to increase volumetric capacity, how may this decision impact the truck's overall performance and lifespan?
💡 Hint: Consider the mechanics of weight distribution and strain on the truck's structure.
