Challenge Problems
Push your limits with advanced challenges
Calculate the effective usable power for a construction machine when given the gross power output and the losses incurred from altitude and resistance. The gross power is 200 HP, with losses at 30 HP due to altitude and resistance issues.
💡 Hint: What do we subtract from the total power?
If a performance chart indicates that a machine can achieve 90% efficiency at sea level but only 70% at a high altitude, what are the potential implications for productivity over continuous operation?
💡 Hint: Consider the efficiency implications over time!
