Vertical Circles Centripetal Acceleration

Click For Summary
SUMMARY

The discussion focuses on calculating the minimum radius of a vertical loop for a jet pilot, given a speed of 840 km/hr (233.3 m/s) and a maximum centripetal acceleration of 6 Gs. The key formula used is centripetal acceleration, expressed as a = v² / r. By rearranging this equation, the minimum radius can be determined to ensure the centripetal acceleration does not exceed the specified limit.

PREREQUISITES
  • Understanding of centripetal acceleration and its formula (a = v² / r)
  • Basic knowledge of forces and Newton's second law (F = ma)
  • Familiarity with units of measurement, particularly converting speed from km/hr to m/s
  • Ability to interpret and analyze free body diagrams (FBD)
NEXT STEPS
  • Calculate the minimum radius using the formula a = v² / r with the given values.
  • Explore the effects of varying speeds on centripetal acceleration in vertical loops.
  • Research the implications of exceeding 6 Gs on pilot safety and aircraft performance.
  • Learn about the dynamics of circular motion in aviation and its applications in flight training.
USEFUL FOR

Aerospace engineers, physics students, flight instructors, and anyone interested in the dynamics of circular motion in aviation.

Homework Statement


A jet pilot takes his aircraft in a vertical loop. V is 840 km/hr (233.3 m/s) find the min. radius of the loop to that the centripetal acceleration at the bottom does not exceed 6 Gs.

Homework Equations


a = v^2 / r
F = ma

The Attempt at a Solution


I don't know where to start. Confused about the Sum part (Fx and Fy)
 
Physics news on Phys.org
Start by drawing a free body diagram of the pilot at the bottom of the circle.

On edit: Actually you don't need the FBD. What is an expression for the centripetal acceleration? Hint: It's one of the relevant equations.
