D. Answer these questions:
a. What services did the Wright bothers offers from the cycle shop?
= From the cycle shops, the Wright brothers sold and repaired bicycles. They replaced spokes, fixed broken chains and sold accessories. Later, they also began to build their own brand of bicycles.
b. How did their cycle business help them to build an aircraft?
= The experiences with braces aided the Weight brothers in the investigations of flight. They used the technology they learned from their bicycle business in their airplanes. Their thoughts on balancing and controlling their aircraft also roooted in their experice as cyclists. Thus, their cycle business help them to build.
c. How did the brothers develop the idea of balance and contral in the flight of an aircraft?
=In the flight of an aircraft, the brothers develop this idea of balance and control by three axes of motion a wing warping system and also by observing buzzards keeping Their balance by twisting their wings and sometimes curving and wing more than the other.
d. What way their first aircraft like?
→ Their first aircraft was like a small kite with a five-foot wingspan that was used to test their notions of aircraft control.
e. What did they do to create the flight canditions?
= To create the flight conditions, they teated small model wings in a wind tunnel they had built.
f. What is "wing warping"?
="Wing Warping was a system which was used to control the aircraft in a roll.
g. When and where did the first flyer take off?
= The first flyer took off at 10:35 am in 1907 at Kill Devil Hills .N.C.
h. What progress had they made they made by 1904?
= They achieved the first circular flight of an airplane on September 20, 1904. This was the progress they had made by 1904.
i. What was the world's first practical airplane like?
= The world's first practical airplane like was Flyer.
