View mutual fund news, mutual fund market and mutual fund interest rates. Unlike attitude and heading gyros that are free to rotate and the instrument senses the orientation of their axis, the turn coordinator (and the turn indicator one) has the axis mounted fixed and the instrument measures the torque forces as the gyroscope tries to resist the rotational motion. These forces create a horizontal torque on the gyroscope, which create a change in angular momentum ΔL that is also horizontal. C. There is also a contact force, Fc , between the end of the axle and the pylon.
