Question

A device for acclimating military pilots to the high accelerations they must experience consists ofa horizontal beam that rotates horizontally about one end while the pilot is seated at the other end. In order to achieve a radial acceleration of 33.9 m/s2 with a beam of length 5.91 m, what rotation frequency is required? Number Hz

Answer 1

the rotational accleration is

a = v^2/ L

a = ( L w)^2/ L

= L w^2

w = root a/L

= root ( 33.9/5.31)

=2.52 rad/s^2

2 pi f = 2.52 rad/s^2

f = 2.52 rad/s^2/ 2 pi

=0.40 Hz

As per guide lines I have done first problem
