The Limiting Velocity in Falling from a Great Height

The Limiting Velocity in Falling from a Great Height

Date: January 1, 1919
Creator: Wilson, Edwin Bidwell
Description: The purpose of this report is to give a simple treatment of the problem of calculating the final or limiting velocity of an object falling in vertical motion under gravity in a resisting medium. The equations of motion are easily set up and integrated when the density of the medium is constant and the resistance varies as the square of the velocity. The results show that the fundamental characteristics of the vertical motion under gravity in a resisting medium is the approach to a terminal or limiting velocity, whether the initial downward velocity is less or greater than the limiting velocity. This method can be used to calculate the terminal velocity of a bomb trajectory.

Periodic stresses in gyroscopic bodies, with applications to air screws

Periodic stresses in gyroscopic bodies, with applications to air screws

Date: January 1, 1918
Creator: Zahm, A F
Description: Report discusses periodic stresses in gyroscopic bodies with applications to air screws caused by particle mass. Report concludes that all modern air screws obey the laws found for plane groups of particles. In particular the two-bladers exert on the shaft a rhythmic gyroscopic torque; the multibladers a steady one; both easily calculable for any given conditions of motion and mass distribution.
