The Pilot Of An Airplane Executes A Vertical Loop Which In Part Follows The Path Of A Four Leaved Rose T 600 Cos 2 2 (8.84 KiB) Viewed 44 times
The pilot of an airplane executes a vertical loop which in part follows the path of a four-leaved rose, T= = (-600 cos 20) ft, where is in radians. His speed at A is a constant up = 80 ft/s. He weighs 145 lb. Hint: To determine the time derivatives necessary to compute the acceleration components a, and ae, take the first and second time derivatives of T= = (-600 cos 20). Then, for further information, use +²+(re)² to determine 8. Also, take the time v= derivative of v= +²+ (r)², noting that up = 0, to determine 0. (Figure 1) Figure 80 ft/s 1 of 1 r=-600 cos 28
Determine the magnitude of the vertical reaction the seat of the plane exerts on the pilot when the plane is at A. Express your answer to three significant figures and include the appropriate units.
