Aircraft Engineering Question:

Sperry's rule of procession describes about the direction in which the procession takes place. This procession is dependent on the direction of rotation for the mass and the axis of the torque that is applied on the material. It provides a guide to the direction of procession that allows easy finding of the direction of the applied torque. This also helps in finding out the direction of the rotation of gyro-wheel. If the torque is applied and is perpendicular to the spin axis then it can be transferred as a force.
