 P: 1 can anyone tell me how to calculate G force of an airplane of mass=79015, velocity=257.2 m/s turning uniformly at a radius of 100 meters. I use the formula as f=mv^2/r i dont know if its correct but i get an answer of f=52269876.376 then i substituted in the equation f=ma .. and i got a= 661.51 m/sec^2 finally i used G=a/g. i got G= 661.51/9.8 and i got 67.5 g's... please help me with this problem .
 Sci Advisor P: 2,470 And now you know why airplanes do not make such turns when traveling at such high speeds. Technically, you've only computed the horizontal component of the loading factor. If you had a smaller load, you'd have to combine it with vertical 1g due to gravity. But in this case, it won't make any difference.
 HW Helper Thanks P: 5,582 It's simple: a plane traveling at 257.2 m/s can't turn this tightly without coming apart. Anyone aboard has already blacked out.
