Answer :
Final answer:
The addition of a gasoline engine allowed the Wright brothers to transition to powered flight, requiring them to learn new steering techniques for altitude control. This was a significant step in their experiments as they moved from gliding to controlled powered flight. Their success relied on mastering the use of this engine for steering and control.
Explanation:
Impact of Gasoline Engines on the Wright Brothers' Experiments
The addition of a gasoline engine significantly transformed the Wright brothers' approach to flight experimentation. Initially, their experiments focused on gliders and various forms of lighter-than-air transport, but with the introduction of a gasoline engine, they entered a new phase of powered flight.
Among the four options provided, the best explanation is that the Wright brothers had to learn how to steer the airship up and down with the power of the engine. This required them to develop new techniques for flight control, as the power of the engine provided them with thrust, which necessitated changes in their steering methods compared to gliding. They had to understand how to effectively use the engine's propulsion to manage altitude and direction, moving beyond simply controlling a glider.
While they did face challenges in terms of weight and design, the primary obstacle was mastering the control of a powered flight system. This was crucial for their eventual success in achieving sustained and controlled flights.
