The wind tunnel made by Wright's brother was made up of a wooden box with glasses on it to see the inner instruments work.
The key factor that made the Wright's brother wind tunnel a useful tool for wind design is the balancing equipment used in it. It was designed to measure lift and drag. Old hacksaw blades and bicycle spokes were used to make the balances which measure the forces of lift and drag action on a wing.
The Wright brothers built a wind tunnel<span> and developed model-testing </span>techniques<span> including a </span>balance to more accurately determine the lift and drag of their aircraft. I hope my answer has come to your help. God bless and have a nice day ahead!
We know that Distance = speed x time Let w be the time Brad spent walking. The time spent jogging will be 1 - w 6 = 5w + 9(1 - w) w = 0.75 hours Distance walked = 0.75 x 5 = 3.75 km
