Question

Take the inner eat to be approximately 7.0 cm from the axis of spin. (The distance varies from person to person) What is the radial acceleration (in m/s^2 and in g's) of the endolymph fluid? A jet plane comes in for a downward dive as shown in Fig E3.25. The bottom part of the part is a quarter circle with a radius of curvature of 280 m. According to medical tests, pilots will lose consciousness when they pull out of a dive at an upward acceleration greater than 5.5g. At what speed (in m/s and in mph)will the pilot black out during this dive?

Explanation / Answer

given radius of curvature R = 280 m

upward accelaration greater than 5.5 g

we have

V2 = 5.5 X g X R

V2 = 5.5 X 9.8 X 280

V2 = 15092

V = 122.84 m/s

speed V in mph

V = 274.78 mph
