The University of Virginia is investigating the use of a magnetohydrodynamic (MHD) angular rate sensor to measure head angular acceleration in impact testing. Output from the sensor, which measures ...

Displacement close displacementA distance measured in a specified direction. is the distance moved in a straight line, in a given direction, from the starting point. Displacement = 24 m east. Velocity ...

A theory based on the distortion of large water drops is used to calculate the drag and acceleration of drops in the laboratory from rest to terminal velocity. The results show that the drag ...
