- f jon The pilot of a crippled jet was able to control his plane by throttling the two engines. The plane has a weight of 17000 lb and a radius of gyration of kg = 4.7ft about the mass center G. Originally the plane is flying straight at a speed of 1200 ft/s. Neglect the effects of 5000 lb as shown, determine: drag and the loss of fuel. If the thrust in each engine is altered to T₁ = 800 lb and T₂ Remark: The counterclockwise sense is the positive sense. 1.25 ft T₂ 1.25 ft T₁ 1:21:02 7Please include explanation. A 6-MW offshore wind turbine has a capacity factor of 40%. It has a height of 120 m, and 107-m long blades. The angular acceleration is 1.388 rad/s2. Assume that the distance from the center of the turbine to the connection with the blade is negligible, and that the turbine starts from rest. At ? = 12 s, calculate the velocity and the acceleration for points (a) at half the length and (b) at the tip of the blade.Jeremy is piayıng Wth ayoya 07 mass mo-aa grams The yo4o String is let aut to length rs=58 am,and hespins the yoyo in a horizontalc\Ycie at a cotant rate 07 Wo=5,6 rads sec.
