Circular Motion: Plane does a loop

AI Thread Summary
A jet pilot is analyzing the minimum radius of a vertical loop while flying at 700 km/hr, which converts to 194.44 m/s. The problem states that the acceleration at the lowest point of the loop should not exceed 6.0g, equating to 58.8 N of force. The relevant equation for centripetal force is Fcentripital = MV^2/R. The discussion emphasizes calculating the radius (R) based on the specified centripetal acceleration. The community encourages the pilot to focus on the relationship between acceleration and radius to solve the problem.

Homework Statement


A Jet pilot takes his aircraft in a vertical loop. if the jet is moving at a speed of 700km/hr at the bottom of the loop, determine the minimum radius of the loop if the acceleration at the lowest point doesn't exceed 6.0g's (this means 6.0 x acceleration due to gravity on earth)


Homework Equations


Fcentripital = MV^2/R


The Attempt at a Solution



All i know is that 700km/hr is 194.44m/s
and i also know that the Fg at the bottom would be -58.8N
I'm totally stuck, help me out thanks

Hi thussain93! Welcome to PF! :smile:

(try using the X2 tag just above the Reply box :wink:)

It just means find R such that the centripetal acceleration is 6 times 9.8. :smile:
 
Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
