Final answer:
Without context or a specific type of aircraft or engine, it's impossible to state a correct maximum power limit for a normal takeoff for two engines since it varies by design and purpose.
Step-by-step explanation:
The question appears to be related to aeronautical engineering and specifically the topic of engine power during an aircraft's takeoff phase. However, the options provided (1000, 2000, 3000, 4000) don't directly answer the question as they are not connected to the context of the examples provided.
The examples talk about different aspects such as the power in megawatts for an airplane engine, the efficiency of an automobile engine and general aircraft design principles regarding lift. Without a clear context or type of aircraft/engine being referred to, it's impossible to provide a correct maximum power limit for a normal takeoff for two engines. The power requirement varies significantly based on several factors including the aircraft's size, weight, design, and purpose.
