This is where I am lost; I know that Fs = mu_s Fn and since Fn is acting inward, it is equal to Fac (centripetal acc.) and therefore Fs = mu_s Fac. However, what can Fac be? I know that Fac = V^2 / r , but that is of no help.
I know that the motorcycle is going horizontal. Therefore, Fs acts upward, Fn acts toward the center of the circle, and Fg acts downward. This isn't where I am having trouble. I have a correct FBD and have labelled all of the forces correctly.
I would really like some real help, since I have been working on this problem for over two hours without an answer. I am not getting the right answer and an algebraic solution for what I attempted above would be helpful. I have a FBD and know where the forces are directed.
[b]1. A local circus act features a motorcycle rider inside a hollow sphere. He accelerates his bike to a maximum velocity in order to allow himself to be able to drive parallel to the ground inside the sphere. The sphere has an inner diameter of 8.00m, the motorcycle and rider have a mass of...
Okay..I was trying to save time. Here is what I have thus far:
EF = Fs - Fg
Therefore: Fs - Fg = mv^2 / r
mu_s x mg - mg = mv^2 / r
mg (mu_s - 1) = mv^2 / r
r mg (mu_s - 1) = mv^2 / r
[r mg (mu_s - 1)] / m = v^2
rg (mu_s -1 ) = v^2
This, however will not give me the minimum velocity...
I have tried this problem multiple times without success. Please provide a full solution. Thanks!
