A 5,347 lb airplane loops at a speed of 267 mi/hr. If the radius of the loop is 2,231 ft, find the lift on the plane (in pounds) at the bottom of this loop.

Answer 1

A 5,347 lb airplane loops at a speed of 267 mi/hr. If the radius of the loop is 2,231 ft, find the lift on the plane (in pounds) at the bottom of this loop.

1mile /hour = 1.467 ft/sec

267 mile /hour = 267*1.467= 391.68 ft/sec

Force at the bottom of loop = mv²/ r = 5347 * 391.68*391.68/ 2231 pound force
